Procedimiento

To a stirred solution of 3 mmol of 2-methylbenzoyl chloride in 10 ml of methylene chloride is added 5 mmol of triethylamine and 3 mmol of 4,10-dihydro-4-(4-aminobenzoyl)-5H-pyrrolo-[1,2-a]thieno[3,2-e]-[1,4]diazepine. The mixture is stirred for 5 hours. The reaction mixture is washed with water, 2N citric acid, NaHCO3, and brine. The reaction mixture 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, m.p. 162°-188° C. (amorphous)
