실험 절차

Triethylamine (0.012 mL, 0.133 mmol) was added to a solution of 6-amino-1-(2,3-difluorobenzyl)-4-(2,2,2-trifluoroethyl)-1,4-diazepan-5-one (45 mg, 0.133 mmol) and 4-nitrophenyl chloroformate (27 mg, 133 mmol) in tetrahydrofuran (2.5 mL) at 0° C. After 1 h, 2-oxo-1-(4-piperidinyl)-2,3-dihydro-1H-imidazo[4,5-b]pyridine dihydrochloride (43 mg, 0.147 mmol) and triethylamine (0.048 mL, 0.532 mmol) were added and the mixture allowed to warm to ambient temperature. After 18 h, the mixture was partitioned between ethyl acetate and water. The organic layer was washed with water (2×), saturated brine, dried over magnesium sulfate, filtered and concentrated. Purification by silica gel chromatography [100% dichloromethane→92% dichloromethane/methanol (10% ammonium hydroxide/methanol)] gave the title compound (67 mg).
