Versuchsvorschrift

Ethyl 3-aminobenzoate (100 mg) was dissolved in tetrahydrofuran (5 ml), the solution was cooled on ice, triphosgene (65 mg) was added thereto at internal temperature 5° C., triethylamine (220 mg) was added thereto at 3 minutes intervals, the mixture was allowed to come to room temperature and stirred for 10 minutes. A solution of 1-(2-toluoylmethyl)-2-oxo-3-amino-5-cyclohexyl-8-methyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepine (820 mg) in tetrahydrofuran (5 ml) was added, additionally stirred for one hour. Water was added to the reaction mixture, extracted with methylene chloride. The organic layer was successively washed with water and saturated brine, dried over anhydrous sodium sulfate, the solvent was evaporated under reduced pressure, the residue was purified by silica gel column chromatography(n-hexane:ethyl acetate=3:1), to thereby obtain 265 mg of the titled compound (Yield 81%).
