Reaktionsschritte

59 g of β-hydroxypropionamide and 75 g of benzylamine were heated with 50 mg of 2,6-di-t-butyl-p-cresol for 7 hours in a temperature range of 120°-170° C. until the evolution of ammonia was complete. After adding 2.2 g of polyphosphoric acid distillation was carried out in an oil pump vacuum; the subsequent redistillation with the addition of 1 ml of sulphuric acid yielded 92 g of N-benzylacrylamide, Bp0.1 113° C., which crystallized in the receiver. Mp (crude product): 53° C.
