Versuchsvorschrift

3-[4-(10,11-Dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine-10-carbonyl)-phenyl]-cyclohex-2-enone of Example 24 (0.100 g, 0.261 mmol) and cerium (III) chloride (0.064 g, 0.261 mmol) were dissolved in methanol (1.3 mL) followed by addition of solid sodium borohydride (0.010 g, 0.261 mmol). After hydrogen evolution ceased (approximately 5 minutes), 0.1 N hydrochloric acid (50 mL) was added and the resulting mixture extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, filtered and concentrated. A slightly yellow solid was isolated which was dissolved in boiling diethyl ether and filtered. The product was precipitated from the filtrate by addition of pentane and the precipitate filtered and dried to afford the title compound (0.100 g) as an amorphous white solid.
