Versuchsvorschrift
To a solution of (3RS)-1-[(3-azabicyclo[3.2.2]non-3-yl)carbonylmethyl]-3-benzyloxycarbonylamino-5-acetoxymethyl-9-methyl-2,3-dihydro-1H-1,4-benzodiazepin-2-one (1.9 g) in ethanol (40 ml) was added 1N-sodium hydroxide solution (7 ml) under stirring at ambient temperature. The mixture was stirred for 20 minutes under the same conditions. After removal of the solvent water was added into the mixture, which was adjusted to pH 4 with a diluted hydrochloric acid and extracted with ethyl acetate twice. The combined extract was washed with water and dried over magnesium sulfate. Removal of the solvent gave (3RS)-1-[(3-azabicyclo[3.2.2]non-3-yl)carbonylmethyl]-3-benzyloxycarbonylamino-5-hydroxymethyl-9-methyl-2,3-dihydro-1H-1,4-benzodiazepin-2-one as an amorphous mass (1.68 g, 95.3%).
