Liver X receptors (LXRs) belong to a family of nuclear hormone receptors that are endogenously activated by cholesterol and its oxidized derivatives to mediate transcription of genes involved in maintaining glucose, cholesterol, and fatty acid metabolism. LXRa is found predominantly in the liver, with low levels found in kidney, intestine, spleen, and adrenal tissue. LXRp is ubiquitous in mammals and was found in nearly all tissues examined. Given the intricate link between lipid metabolism and cancer cell growth, the ubiquitous expression of LXRp in some types of cancer is unlikely to be coincidental, allowing cancer cells to synthesize lipids and lipoprotein particles to sustain their growth. At the same time, however, such stable basal expression levels make LXRp an ideal therapeutic target.

To a 1 L 3-necked round bottom flask under nitrogen was added 2-(1-(4-bromo-2-fluorophenyl)-2-(2-(2,6-dichlorophenyl)propan-2-yl)-1H-imidazol-4-yl)propan-2-ol (12.0 g, 24.7 mmol), [2-fluoro-6-methanesulfonyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-methanol (9.78 g, 29.6 mmol), K2CO3 (10.2 g, 74 mmol), DME (120 mL) and water (12 mL). The mixture was heated to 60° C., and then 1,1′-bis(diphenylphosphino)ferrocene palladium (II) chloride complex (4.06 g, 4.94 mmol) was added under nitrogen. The reaction mixture was heated to 80° C. for 30 minutes. The resulting darkly colored mixture was cooled with an ice bath, and partitioned in 200 mL of CH2Cl2 and 200 mL of water. The organic layers were combined and dried with Na2SO4. After concentration, the crude product was purified by flash chromatography (ISCO, 330 g silica, 0% to 100% EtOAc in hexanes) to afford 12.79 g of crude product (85% yield) as a light yellow solid.

Recrystallization was carried out by dissolving 9.5 g of crude product in acetone (80 mL) at 65° C. The resulting solution was cooled slowly to 25° C. over 5 hours, and then cooled to 0° C. for an additional 30 minutes. Crystals began to form at 45° C. The solid was collected by filtration and rinsed with cold acetone. After drying in an oven at 45° C. under vacuum for 14 hours, 4.9 g of pure product was obtained. To recover additional crystalline product, the mother liquid was concentrated to approximately 10 mL and passed through a silica pad. EtOAc (100 mL) was used to elute the compound. The filtrate was concentrated under vacuum to give a crude solid. The crude solid was recrystallized in acetone following the procedure above to afford an additional 2.5 g of product. The combined recovery for the two crops after recrystallization was a 78% yield. 1H-NMR (DMSO-d6, 400 MHz) δ 7.94 (m, 2H), 7.63 (dd, 1H, J=11.29, 1.51 Hz), 7.34 (d, 1H, J=9.54 Hz), 7.14 (m, 3H), 7.05 (m, 1H), 6.83 (s, 1H), 5.58 (t, 2H, J=5.27 Hz), 4.96 (d, 2H, J=4.27 Hz), 4.70 (s, 1H), 3.46 (s, 3H), 1.96 (s, 6H), 1.45 (s, 6H); MS m/e 609.16 (M+H+); HPLC (XBridge 5μ C18 4.6×50 mm, 4 mL/min, Solvent A: 10% MeOH/water with 0.2% H3PO4, Solvent B: 90% MeOH/water with 0.2% H3PO4, gradient with 0-100% B over 4 minutes): 2.56 minutes.

Alternatively, Example 9 was prepared as follows:

To a 1 L 3-necked round bottom flask under nitrogen was added methyltetrahydrofuran (“MeTHF”, 6.9 kg), 2-(1-(4-bromo-2-fluorophenyl)-2-(2-(2,6-dichlorophenyl)propan-2-yl)-1H-imidazol-4-yl)propan-2-ol (1.994 kg, 4.1 moles) and (2-fluoro-6-(methylsulfonyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)methanol (1.38 kg, 4.19 moles). The mixture was agitated at 23° C. for 15 min until all the solids dissolved. At the conclusion of this period, (oxydi-2,1-phenylene)bis(diphenylphosphine) (0.022 kg, 0.041 moles) and Pd(OAc)2 (0.01 kg, 0.045 moles) were added as a slurry via a subsurface line. Upon completion of addition, the mixture was rinsed with additional MeTHF (1.65 kg). The resulting mixture was evacuated to less than 80 Torr and backfilled with nitrogen. This process was repeated two more times. After completion of the degassing sequence, the reaction mixture was agitated for at least 15 min and a clear, golden color was observed. In a separate reaction vessel, a solution of potassium hydroxide (0.352 kg) in water (10.00 kg) was prepared and degassed by sparging the solution with nitrogen gas for at least 15 min prior to use. The KOH solution (10.35 kg) was transferred into the reactor by vacuum. The reaction temperature exhibited a known exotherm from 20° C. to 29° C. Upon completion of addition, the resulting biphasic mixture was degassed by a series of pressure swings. The mixture was warmed to between 45-50° C. where it was stirred for at least 2 h. After this time, the reaction mixture was analyzed by HPLC, which indicated the reaction was complete. The reaction mixture was cooled to 23° C. and the stirring was stopped. The mixture was allowed to separate for 30 min and the lower spent KOH stream was removed. The product rich organic was passed through a column of thiourea functionalized silica gel (0.782 kg) (Silicycle) at ˜0.1 kg per min to remove the palladium. The product rich organic phase was washed with a 5% NaHCO3 solution (5 vol) and the phases separated. The organic phase was washed with water (5 vol) and the organic and aqueous phases separated.

The product rich organic phase was polish filtered into a clean reaction vessel and then concentrated to ˜8 volumes (˜16 L) under vacuum (80 Torr, Tjacket=60° C.). Once at the prescribed volume, the reaction mixture was allowed to cool to 25° C. Once at the prescribed temperature the reaction mixture was seeded with 2-(2-(2-(2,6-dichlorophenyl)propan-2-yl)-1-(3,3′-difluoro-4′-(hydroxymethyl)-5′-(methylsulfonyl)biphenyl-4-yl)-1H-imidazol-4-yl)propan-2-ol (0.5%, 0.008 kg). The resulting slurry was stirred at 25° C. for about 18 h. At the conclusion of this period, the reaction mixture was concentrated to ˜8 L under vacuum (150 Torr, Tjacket=60° C.). Once at the prescribed volume, the reaction mixture was heated to 50° C. and isopropyl acetate (IPAc, 13.90 kg) was added to the reactor during a 90 min period. Upon completion of addition, the reaction mixture was cooled to 25° C. during a 3 h period. Once at the prescribed temperature the reaction mixture was stirred at room temperature for about 16 h. At the conclusion of this period, the reaction mixture was filtered, deliquored, and washed with additional IPAc (10.4 kg). The filter cake was dried via suction on the filter under a stream of dry nitrogen to yield a white solid. The white solid was transferred to a dryer and dried at 50° C. under full vacuum to afford 2.03 kg of product (81% yield, 99.40 AP, 98 wt %).

PAPER

Abstract Image

Introducing a uniquely substituted phenyl sulfone into a series of biphenyl imidazole liver X receptor (LXR) agonists afforded a dramatic potency improvement for induction of ATP binding cassette transporters, ABCA1 and ABCG1, in human whole blood. The agonist series demonstrated robust LXRβ activity (>70%) with low partial LXRα agonist activity (<25%) in cell assays, providing a window between desired blood cell ABCG1 gene induction in cynomolgus monkeys and modest elevation of plasma triglycerides for agonist 15. The addition of polarity to the phenyl sulfone also reduced binding to the plasma protein, human α-1-acid glycoprotein. Agonist 15 was selected for clinical development based on the favorable combination of in vitroproperties, excellent pharmacokinetic parameters, and a favorable lipid profile.
