실험 절차

To a solution of 4-(dimethylamino)-benzaldehyde (10.0 g, 67.03 mmol) in dichloromethane (250 mL) was added pyridinium tribromide (21.4 g, 67.03 mmol). The reaction mixture was stirred at room temperature overnight. The solution was washed successively with water and brine, dried over anhydrous magnesium sulfate, filtered and evaporated. Chromatography on silica gel (15% EtOAc in hexane) afforded 14.06 g of 3-bromo-4-(dimethylamino)-benzaldehyde (92%).
