実験手順

DIPEA (181 μL, 1.035 mmol) was added to a mixture of 6-chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-(1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-5-yl)nicotinamide (Stage 36.1, 100 mg, 0.207 mmol), methyl-3-pyrrolidine carboxylate hydrochloride (44.5 mg, 0.269 mmol) and iPrOH (414 μL). in MW vial, which was flushed with argon, sealed and stirred at 130° C. for 24 h. The RM was diluted with EtOAc, treated with brine and extracted with EtOAc. 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 (Silica gel column, n-heptane/EtOAc from 40% to 100% EtOAc) followed by preparative TLC (Silica gel, eluent EtOAc). Additional lyophilization from 1,4-dioxane afforded the title compound as a white light solid.
