실험 절차

To a solution of 318 mg of 3-methyl-2-thiophenecarbonyl chloride in 5 ml of methylene chloride at 0° C. is added 346 μl of triethylamine. After stirring for 3 minutes, 500 mg of the 10,11-dihydro-10-(4-aminobenzoyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine is added. The bath is removed and the reaction mixture stirred at room temperature for 18 hours. The volatiles are concentrated in vacuo to give a residue which crystallizes from ethyl acetate to afford 800 mg of solid. The solid is dissolved in methylene chloride washed with water, 2N citric acid, 1M NaHCO3 and brine. The organic layer is filtered through hydrous magnesium silicate, dried with Na2SO4 and concentrated in vacuo to give a residue which crystallizes from ethyl acetate to afford 400 mg of the desired product as a white solid, m.p. 232°-235° C.
