실험 절차
0.5 g of 7-bromo-1-(4-nitrophenyl)-4-methyl-8-methoxy-5H-2,3-benzodiazepine (Example 3, Step C) is suspended in 15 ml of benzene, mixed with 0.53 g of potassium carbonate and 0.17 ml of cyclopropylcarboxylic acid chloride and then refluxed for 5 hours. Then, the mixture is stirred with water, the organic phase is separated, washed in succession with soda solution and water, dried, filtered and concentrated by evaporation. The residue is purified by absorptive precipitation in ethanol, and 0.38 g of 7-bromo-3-cyclopropylcarbonyl-1-(4-nitrophenyl)-4-methyl-8-methoxy-3H-2,3-benzodiazepine of the title compound with a melting point of 231-223° C. is obtained.
