General Scheme for Examples 252 and 253:

Example 252

Step 1

A mixture of cesium carbonate (149 mg, 0.457 mmol), Xantphos (14.43 mg, 0.025 mmol), Pd 2(dba) (11.42 mg, 0.012 mmol), 6-chloro-N-(methyl-d3)-4-((3-(methylthio)pyridin-2-yl)amino)pyridazine-3-carboxamide (65 mg, 0.208 mmol), and (R)-spiro[2.2]pentane-1-carboxamide (50.8 mg, 0.457 mmol) in dioxane (3 mL) was degassed using a vacuum/N2 fill cycle three times. The reaction was heated at 110° C. for 16 hours. The reaction was diluted with water and DCM. The DCM layer was separated and washed two more times with water and then dried (Na 2SO 4), filtered and concentrated. Purification via automated flash chromatography, eluting with methanol in DCM from 0 to 10%, gave the title compound (R)—N-(methyl-d3)-4-((3-(methylthio)pyridin-2-yl)amino)-6-(spiro[2.2]pentane-1-carboxamido)pyridazine-3-carboxamide (54 mg, 67% yield). 1H NMR (400 MHz, CHLOROFORM-d) δ 12.15 (br s, 1H), 9.88 (s, 1H), 8.68 (br s, 1H), 8.36 (br d, J=3.5 Hz, 1H), 8.25 (br s, 1H), 7.72 (br d, J=7.4 Hz, 1H), 6.97 (br dd, J=7.0, 5.1 Hz, 1H), 2.51 (s, 3H), 2.21-2.09 (m, 1H), 1.58-1.10 (m, 6H), 1.08-0.93 (m, 5H).
      LCMS (ESI) m/e 388.1 [(M+H) +, calc’d C 18183621, 388.1]; LC/MS retention time (method D): t R=0.80 min.

Step 2

To a suspension of hydrogen peroxide (30% solution in water, 0.258 mL, 2.52 mmol) and (R)—N-(methyl-d3)-4-((3-(methylthio)pyridin-2-yl)amino)-6-(spiro[2.2]pentane-1-carboxamido)pyridazine-3-carboxamide (0.0489 g, 0.126 mmol) in AcOH (1 mL) was added sodium tungstate dihydrate (0.042 g, 0.126 mmol) at room temperature. After stirring at room temperature for 1 hour, the reaction was diluted with water, basified with Na 2CO powder and extracted three times with DCM. The DCM layers were combined, washed with Na 22(5% solution), dried (Na 2SO 4), filtered and concentrated. The crude product was purified using reverse phase prepHPLC to give the title compound (R)—N-(methyl-d3)-4-((3-(methylsulfonyl)pyridin-2-yl)amino)-6-(spiro[2.2]pentane-1-carboxamido)pyridazine-3-carboxamide (16.2 mg, 31%) as a colorless solid. 1H NMR (500 MHz, DMSO-d 6) δ 12.07 (s, 1H), 11.22 (s, 1H), 9.49 (s, 1H), 9.16 (s, 1H), 8.63 (dd, J=4.6, 1.5 Hz, 1H), 8.29 (dd, 0.1=7.8, 1.4 Hz, 1H), 7.34 (dd, 0.1=7.8, 4.7 Hz, 1H), 2.48-2.43 (m, 1H), 1.46-1.41 (m, 1H), 1.42-1.36 (m, 1H), 0.95-0.82 (m, 3H), 0.80-0.73 (m, 1H). (3H methyl sulfone was buried under DMSO peak). LCMS (ESI) m/e 420.0 [(M+H) +, calc’d C 1818364S, 420.1]; LC/MS retention time (method E): t R=1.38 min; OR: −205.39 (20° C.).
