반응 단계
A mixture of 0.90 g (9.26 mmol) of potassium thiocyanate, 2.00 g (6.15 mmol) of (±)-8-methyl-5-(4-nitrophenyl)-8,9-dihydro-7H-1,3-dioxolo[4,5-h][2,3]benzodiazepine and 40 ml of acetic acid was stirred at 100-110° C. for 6 h. After cooling, the precipitated crystals were filtered off, washed with water and dried to yield 1.80 g (76%) of the title compound. Mp.: 242-243° C.
