Versuchsvorschrift

To a solution of 2,2,2-trichloro-1-{10-[(3-methoxy-2′-methyl[1,1′-biphenyl]-4-yl)carbonyl]-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-3-yl}ethanone of Step E (1.6 g, 2.9 mmol) in acetone (20 mL) was added 2.5 N sodium hydroxide (2.3 mL, 5.8 mmol). After stirring overnight, the reaction was acidified with 2 N hydrochloric acid (3.2 mL, 6.4 mmol) then concentrated in vacuo. The residue was partitioned between ethyl acetate and water. The layers were separated, and 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 1.2 g of desired product as an off-white solid, m.p. 201–204° C.
