Rongliflozin L-pyroglutamic acid, a highly active SGLT-2 inhibitor cocrystal discovered and developed by our group, is currently undergoing clinical trials for the treatment of diabetes. Here, we report and design a simple and robust process to obtain a single and pure crystalline form I (1) of the cocrystal, containing Rongliflozin (2) with L-pyroglutamic acid (L-PA), based on coformer-induced purification (CoIP). Extensive experiments showed that the addition of L-pyroglutamic acid in the eluent was key to suppression of the dissociation equilibrium of the cocrystal during lessivation, with high efficiency. Importantly, based in this profile, this process exhibited strong robustness and margin of safety at multigram and multikilogram scales
Kilogram scale Process of 1
A mixture of (1R,2S,3S,4R,5S)-5-(4-chloro-3-(4-ethoxybenzyl) phenyl)-1-((R)-1-
hydroxyethyl)-6,8-dioxabicyclo [3.2.1] octane-2,3,4-triol ethanolate form III (3) (23.45 kg, 47.3
mol), L-pyroglutamic acid (24.31 kg, 4.0 equiv.), EtOH (35.9 L) and H2O (70 L) was added into a
300 L reactor at room temperature. The slurry was heated to 65 °C and stirred until it is clear. The
clear solution was cooled to 35±5 °C typically. Seed crystal form I (1) (0.70 kg, 3% g/g) was added
when the solution was cooled to 34 °C and maintained for 1.5 h. Gradually, the slurry was cool to
30 °C and 25 °C in 3 hours, and finally stirred at 25 °C for 24 h. The slurry was collected on a
centrifuge filter. The filter cake was washed with a mixed solution of EtOH (31.3 L)/H2O (62.7 L)
with L-pyroglutamic acid (1.64 kg, 7% g/g) pre-cooled to -15°C. The wet cake was dried under
vacuum at 45 °C for 8 h. Pure cocrystal form I (1) was obtained as a white solid (24.91 kg, yield
91%). MP (DSC onset) = 96.91 ℃. 1H NMR (599 MHz, DMSO-d6) δ 12.77 (br, 1H), 7.91 (s, 1H),
