실험 절차

Methyl 5-amino-2-fluorobenzoate (241 mg) was dissolved in tetrahydrofuran (43 ml), under ice-cooling triphosgene (142 mg) was added and triethylamine (123 μl) were added five times every 3 minutes, a solution of 1-(2-toluoylmethyl)-2-oxo-3-amino-5-pivaloyl-8-methyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepine (528 mg) in tetrahydrofuran (20 ml) was added thereto, and the mixture was allowed to come to room temperature and stirred at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure, water (50 ml) was added, and extracted with methylene chloride. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography(n-hexane:ethyl acetate=2:1), to thereby obtain 543 mg of the titled compound (Yield: 69.3%).
