Procedure

A solution of 0.83 g of 10,11-dihydro-10-(4-amino-3-methylbenzoyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine, 0.5 g of N,N-diisopropylethylamine and 0.6 g of 2-methylbenzoyl chloride in 50 ml of methylene chloride is stirred at room temperature for 18 hours. The reaction mixture is washed with water, the organic layer dried with Na2SO4 and passed through a pad of hydrous magnesium silicate. Hexane is added at the boil to give 0.75 g of a solid which is crystallized from methylene chloride-hexane to give 0.61 g of the desired product, m.p. 125°-130° C.
