3-氨基苯甲酸丁酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In a three-necked flask equipped with a dropping funnel, a thermometer and a reflux condenser 15.4 g of n-butyl 3-aminobenzoate was placed and 150 ml of toluene was added thereto with stirring to dissolve n-butyl 3-aminobenzoate therein. With stirring the resultant mixture by a magnetic stirrer, 17.3 g of p-toluenesulfonylisocyanate was added dropwise to the mixture through the dropping funnel at room temperature. Continuous stirring of the reaction mixture caused an exothermic reaction, thereby precipitating a large amount of white solid. In a three-necked flask equipped with a dropping funnel Continuous stirring of the reaction mixture an exothermic reaction precipitating a large amount of white solid
