A mixture of 0.806 g (0015 mol) of 10-{[2′-(cyanomethyl)-1,1′-biphenyl-4-yl]carbonyl}-N-(pyridin-3-ylmethyl)-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine-3-carboxamide of Example 17, 0.52 g (0.0075 mol) of hydroxylamine hydrochloride and 1.03 g (0.0075 mol) of potassium carbonate in 100 mL of ethanol and 25 mL of water was heated under reflux for 2 hours. An additional 1.04 g (0.015 mol) of hydroxylamine hydrochloride and 2.06 g (0.015 mol) of potassium carbonate was added to the and refluxing was allowed to continue until LC/MS indicated that all the starting nitrile was consumed. The solvents were removed in vacuo and the residue was washed with water and purified by chromatography to provide the title compound (0.191 g), m.p. 131-134° C.
