実験手順

2-Chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5′-fluoro-[3,3′-bipyridine]-5-carboxamide (Stage 266.1, 70 mg, 0.160 mmol) and DIPEA (0.196 mL, 1.121 mmol) were added to a vial containing iPrOH (2 mL). (3S,4S)-4-Aminopyrrolidin-3-ol (30 mg, 0.168 mmol) was added. The mixture was stirred at 80° C. for 44 h. The RM was treated with sat. aq. Na2CO3 (20 mL) and extracted with EtOAc. The combined extracts were washed with brine (10 mL), dried over Na2SO4, filtered and evaporated to dryness under reduced to give the crude product which was purified by flash chromatography (Silica gel column, 4 g, DCM/MeOH, from 95:5 to 8:2) to afford the title product as a beige solid.
