In a reactor equipped with a motor-driven stirrer, 45 g of water, 1.38 g of sodium hydroxide (reagent, purity: 96%) and 43.56 g of p-aminomethylbenzonitrile were charged in this sequence and then stirred at room temperature. 74.8 g of 30 wt % hydrogen peroxide water was gradually added so that the reaction temperature reaches 30° C. or lower, followed by mixing with stirring. After foaming and temperature rise were terminated, the reaction solution was cooled to 5° C. The deposited crystal was collected by filtration and then dried to obtain 41.92 g of p-aminomethylbenzamide (yield based on p-aminomethylbenzonitrile: 81%). The purity of p-aminomethylbenzamide determined by analyzing using high-performance liquid chromatograph was 97%.
