Reaction Steps

Silver nitrate (0.3 g, 2.00 equiv) was added to a stirred solution of ethyl 4-bromo-9-iodo-4,5-dihydrobenzo[b]pyrazolo[1,5-d][1,4]oxazepine-2-carboxylate (400 mg, 0.86 mmol, 1.00 equiv) in acetone (20 mL)/water (20 mL) was added. The resulting mixture was stirred for 12 hours at room temperature, diluted with water, extracted with ethyl acetate, dried over anhydrous sodium sulfate, and concentrated under vacuum. The residue was purified by a silica gel column with ethyl acetate/petroleum ether (1:3) to give 0.12 g (35%) of the titled compound as a white solid. LC-MS (ES, m/z) 401[M+H]+.
