N-(亚苄基氨基)苯磺酰胺

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

实验步骤: A four neck flask (1 liter) equipped with a thermometer, a reflux condenser and a stirrer was charged with 86 g (0.5 mol) of benzenesulfonohydrazide and 700 ml of methanol, and 63.6 g (0.6 mol) of benzaldehyde was dropwise added thereto in one hour while stirring at room temperature and heated under reflux for about 5 hours. The reaction liquid was cooled down to 20° C. or lower, and then crystal was filtered off and dried under reduced pressure, whereby white crystal was obtained. A four neck flask (1 liter) equipped with a thermometer, a reflux condenser and a stirrer was dropwise added heated under reflux for about 5 hours The reaction liquid was cooled down to 20° C. lower, and then crystal was filtered off dried under reduced pressure, whereby white crystal was obtained
