Procedure

6-Chloro-5-(pyrimidin-5-yl)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 223.1, 60 mg, 0.149 mmol) and DIPEA (0.182 mL, 1.043 mmol) were added to a vial containing iPrOH (1 mL). (3S,4S)-4-(Dimethylamino)pyrrolidin-3-ol (50 mg, 0.246 mmol) was added. The mixture was stirred at 110° C. for 16 h. The RM was treated with sat. aq. Na2CO3 (20 mL) and was extracted with EtOAc. The combined extracts were washed with brine (10 mL), dried over Na2SO4, filtered and the filtrate was evaporated off under reduced pressure to give a crude product that was purified by preparative SFC (Column DEAP, from 13% to 18% in 6 min) to afford the title product as a white solid.
