実験手順: 103.1 g (1.0 mole) of 3-methoxypropionamide are heated with 104.1 g (1.05 mole) of cyclohexylamine for 8 hours in a temperature range of 130°-170° C. until the evolution of ammonia is complete. The mixture is allowed to cool, 1.5 g of sodium hydroxide is added and the mixture is heated in a high vacuum at 90°-110° C. The methanol is split off within about 30 minutes, vigorous foaming occurring. The temperature is increased and 93.5 g (0.61 mole=61% of the theoretical yield) of N-cyclohexylacrylamide having a Bp0.1 of 124°-128° C., which solidifies into crystalline form in the receiver, are distilled off. to cool the mixture is heated in a high vacuum at 90°-110° C The methanol is split off within about 30 minutes The temperature is increased

実験手順: 59 g of β-hydroxypropionamide and 69.4 g of cyclohexylamine were heated with 50 mg of 2,6-di-t-butyl-pcresol for 5 hours in a temperature range of 130°-170° C. until the evolution of ammonia was complete. After adding 2.5 g of polyphosphoric acid the reaction mixture was maintained at 164° C. for 1 hour and then distilled in a water jet vacuum. The main run was taken off between 140° and 160° C. at 11 bar and crystallized in the receiver. distilled in a water jet vacuum was taken off between 140° and 160° C. at 11 bar crystallized in the receiver
