실험 절차

Triethylamine (0.45 mL, 3.25 mmol) was added to a solution of tert-butyl (3R,6S)-6-(2,3-difluorophenyl)-2-thioxoazepan-3-ylcarbamate (416 mg, 1.62 mmol) and 4-(2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-1-yl)piperidine-1-carbonyl chloride (466 mg, 1.66 mmol) in dichloromethane (70 mL) and the mixture heated to reflux. After 18 h, the mixture was allowed to cool to ambient temperature and concentrated. Purification by silica gel chromatography (100% dichloromethane o 95% dichloromethane/methanol) gave the title compound (685 mg). MS 501.0 (M+1).
