Procedure

1-(2-Toluoylmethyl)-2-oxo-3-tert-butoxycarbonylamino-5-(furan-2-ylcarbonyl)-8-methyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepine (1.00 g) was dissolved in 4N HCl-dioxane (10 ml), the solution was stirred for one hour at 50° C. The reaction mixture was concentrated under reduced pressure, the residue was dissolved in water, the solution was washed with diethyl ether, alkalified with saturated aqueous sodium bicarbonate, and extracted with methylene chloride. The organic layer was dried over anhydrous sodium sulfate, the solvent was evaporated under reduced pressure, to thereby obtain 875 mg of the titled compound (Yield: 100%).
