A 500-ml flask equipped with a distillation column, stirrer, thermometer and dropping funnel was charged with 193.7 g (1.2 mol) of hexamethyldisilazane and 7.0 g (0.02 mol) of dodecylbenzenesulfonic acid. To the flask kept at 70° C., 114.2 g (2.0 mol) of allylamine was added over one hour from the dropping funnel. The contents were stirred for 3 hours under reflux. Subsequently, the allylamine was distilled off over 8 hours. From the reaction solution, a fraction of 89 to 90° C. at 40 mmHg was collected by vacuum distillation, yielding 192.0 g of N,N-bis(trimethylsilyl)allylamine.
