실험 절차

3-Hydroxyazetidine hydrochloride (53.2 mg, 0.486 mmol) and DIPEA (0.170 mL, 0.972 mmol) were added to a suspension of 6-chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-(1H-pyrazol-5-yl)nicotinamide (Stage 48.1, 100 mg, 0.243 mmol) in iPrOH (0.5 mL) and the RM was heated at 140° C. for 3 h. The RM was treated with water, extracted with EtOAc, and the combined extracts were dried over Na2SO4 and the solvent was evaporated off under reduced pressure to give. the crude product which was purified by flash chromatography (RediSep® Silica gel column, 24 g, DCM/MeOH 9:1) to give the title product as a yellow foam.
