実験手順

A solution of 10-[(2-methoxy-2′-methyl-1,1′-biphenyl-4-yl)carbonyl]-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine of Step E (21 mmol) and triethylamine (43 mmol) in anhydrous dichloromethane (45 mL) was cooled in an ice bath. To the stirred solution was added, dropwise, trichloroacetyl chloride (65 mmol). The mixture was allowed to stir at ambient temperature for 72 hours, then was washed with 0.1 N hydrochloric acid and brine, and dried over anhydrous sodium sulfate. Evaporation yielded a foam that solidified by heating with ethyl acetate and chloroform to provide 10.2 g (85%) of the title compound as a white solid, m.p. 221-222° C. MS [(+)ESI, m/z]: 553 [M+H]+
