반응 단계

Triethylamine (100 μL, 0.720 mmol) was added to a solution of the bis hydrochloride salt of (3R,6S)-3-amino-6-(2,3-difluorophenyl)-1-(2,2,2-trifluoroethyl)azepane-2-thione (90 mg, 0.240 mmol) and 4-(2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-1-yl)piperidine-1-carbonyl chloride (74 mg, 0.264 mmol) in dichloromethane (10 mL) and the mixture heated to reflux. After 18 h, the reaction was allowed to cool to ambient temperature, water was added and the mixture was extracted with dichloromethane (3×). The combined organic extracts were dried over sodium sulfate, filtered, and concentrated. Purification by silica gel chromatography (100% dichloromethane→95% dichloromethane/methanol) gave the title compound (78 mg). MS 583.2 (M+1).
