실험 절차

To a solution of 1.84 g of 10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine in 25 ml of methylene chloride is added 1.30 g of N,N-diisopropylethylamine. While cooling in an ice bath, a solution of 3.45 g of [4-[(2-methyl-5-fluorobenzoyl)amino]-2-chlorobenzoyl chloride in 50 ml of methylene chloride is added. The reaction mixture becomes homogeneous after 5 minutes and is stirred at room temperature for 18 hours. Water is added and the separated organic layer washed with saturated sodium bicarbonate, dried with Na2SO4 and passed through a short pad of hydrous magnesium silicate. The methylene chloride is removed in vacuo to give 4.60 g of the desired product as a glass. A sample is crystallized from ethyl acetate to give crystalline solid, m.p. 191°-195° C.
