Versuchsvorschrift

To a solution of 2,2,2-trichloro-1-(10-{[2-methyl-2′-trifluoromethyl-[1,1′-biphenyl]-4-yl]carbonyl}-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-3-yl)ethanone of Step E (2.3 g, 3.9 mmol) in acetone (20 mL) was added 2.5 N sodium hydroxide (3.1 mL, 7.8 mmol). After stirring overnight, the reaction mixture was acidified with 2 N hydrochloric acid (4.3 mL, 8.6 mmol) and then concentrated in vacuo. The residue was partitioned between ethyl acetate and water. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to give a brown solid. Trituration with diethyl ether/hexane provided the title compound (1.32 g) as a white solid, m.p. 233-235° C.
