실험 절차

To a stirred solution of 5 mmol of 2-methylbenzoyl chloride in 10 ml of methylene chloride is added 7 mmol of triethylamine and 5 mmol of 6,7-dihydro-5-(4-aminobenzoyl)-5H-pyrrolo[1,2-a]-[1,5]benzodiazepine. The reaction mixture is washed with water, 2M citric acid, NaHCO3, and brine. The organic layer is dried with Na2SO4, filtered and evaporated in vacuo to give a solid which is purified by flash chromatography on silica gel to give the desired product as a solid; mass spectrum (CI): 422 (M+H).
