Reaction Steps

900 mg of 8-methyl-5-(4-nitrophenyl)-11H-1,3-dioxolo[4,5-h]imidazo[1,2-c][2,3]benzodiazepine is mixed in 10 ml of dimethylformamide with 441 mg of N-bromosuccinimide and stirred for 1.5 hours at room temperature. After dilution with 40 ml of water, the precipitated product is suctioned off, and 900 mg of 9-bromo-8-methyl-5-(4-nitrophenyl)-11H-1,3-dioxolo[4,5-h]imidazo[1,2-c][2,3]benzodiazepine is obtained.
