Participants

Reaction Steps

Triethylamine (40 μL, 0.285 mmol) was added to a solution of the hydrochloride salt of (6S,9R)-6-(2,3-difluorophenyl)-3-(2,2,2-trifluoroethyl)-6,7,8,9-tetrahydro-5H-imidazo[1,2-a]azepin-9-amine (33 mg, 0.095 mmol) and 4-nitrophenyl chloroformate (19 mg, 0.095 mmol) in dichloromethane (2 mL) at 0° C. After 15 min, a solution of the hydrochloride salt of 3-piperidin-4-ylpyridin-2(1H)-one (23 mg, 0.105 mmol) in dichloromethane (1 mL) and triethylamine (26 μL, 0.19 mmol) were added and the mixture was allowed to warm to ambient temperature. After 3 h, saturated aqueous sodium carbonate was added and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium bicarbonate (3×), saturated brine, dried over magnesium sulfate, filtered and concentrated. Purification by silica gel chromatography (100% dichloromethane→90% dichloromethane/methanol) gave the title compound (8.5 mg). MS 650.2244 (M+1).
