Procedure

The 4-[[10,11-dihydro-10-[[2-methyl-2′-trifluoromethyl-[1,1′-biphenyl]-4-yl]carbonyl]-5H-pyrrolo[2,1-c][1,4]benzodiazepin-3-yl]carbonyl]-1-piperazine-carboxylic acid, tert-butyl ester of Example 6 (0.85 g, 1.29 mmol) was added in one portion to stirred ethyl acetate (10 mL) saturated with hydrogen chloride gas at 0° C. A precipitate formed after several minutes. The reaction mixture was stirred for 90 minutes under anhydrous conditions. The reaction was then warmed to room temperature and diluted with diethyl ether. The precipitated product was collected by filtration and dried under high vacuum to provide the desired title compound hydrochloride salt (0.65 g) as an off-white foam.
