Procedure

Methyl 2-methyl-5-aminobenzoate (0.37 g) was dissolved in tetrahydrofuran (10 ml), triphosgene (0.22 g) was added at internal temperature 5° C., triethylamine (0.95 g) was added thereto over 10 minutes, the mixture was stirred at room temperature for 10 minutes. A solution of 1-(2-toluoylmethyl)-2-oxo-3-amino-5-(2-thenoyl)-8-methyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepine (0.81 g) in tetrahydrofuran (10 ml) was added, the mixture was stirred at room temperature for one hour. Water was added to the reaction mixture, and extracted with chloroform. The organic layer was successively washed with water and saturated brine and dried over anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography(chloroform:methanol=50:1), to thereby obtain 1.17 g of the title compound as light yellow amorphous (Yield: 100%).
