Abstract
Drug intermediates o-aminobenzaldehyde synthesis method, comprises the following steps: the reaction vessel was added 2 mol o-nitrobenzaldehyde, 50 L water, 3-4 mol cuprous chloride, 5-6 mol 2-aminotoluene, the stirring rate was controlled at 90-130 rpm, and the temperature of the solution was raised to 70-75°C, reaction for 70-90min, vacuum distillation, collecting fraction of 80-86°C, collecting distillate, add 1-2kg potassium bromide, reduce the solution temperature to 5-8°C, after the crystal precipitated, filter it, washed with the dimethylmine solution and with trifluoroaceticacid solution, dehydrating with the dehydrating agent and recrystallized in the ethane solution to obtain the finished product.
