실험 절차

To a stirred solution of 0.15 g of 10,11-dihydro-10-(4-aminobenzoyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine in 2 ml of methylene chloride is added 0.10 g of triethylamine followed by 0.10 g of isobutylchloroformate. The reaction mixture is stirred for 3 hours and then quenched with 1N NaOH. The organic layer is evaporated in vacuo to a residue which is stirred in 5 ml of tetrahydrofuran for 1 hour, then evaporated in vacuo to a residue. The residue is extracted with ethyl acetate-methylene chloride, washed with brine, dried (Na2SO4), filtered through hydrous magnesium silicate and evaporated in vacuo to give a residue which is stirred with ethyl acetate-methylene chloride to give 0.22 g of cream colored solid. MS(CI): 404 (M+H).
