실험 절차

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.
