실험 절차

38.8 g of potassium carbonate was added to a solution of 50 g of 5-dimethylamino-2,3,4,5-tetrahydro -1H-benzoazepine dissolved in 400 ml of acetone and 200 ml of water. To the solution was added 40 g of p-nitrobenzoyl chloride with ice-cooling and stirring. The resulting mixture was stirred overnight at room temperature. The reaction mixture was mixed with an appropriate amount of water. The resulting crystals were collected by filtration and dried to obtain 71 g of 5-dimethylamino-1-(4-nitro-benzoyl)-2,3,4,5-tetrahydro -1H-benzoazepine.
