Reaktionsschritte

A mixture of 500 ml of benzene and 99 g of cyclohexyl amine were introduced over 30 minutes to 84 g of diketene and after stirring for 4 hours at 20° C., the mixture was evaporated to dryness by distillation under reduced pressure. The residue was taken up in isopropyl ether and the solution was cooled and vacuum filtered. The recovered precipitate was dried and crystallized from isopropyl ether to obtain 137 g of N-cyclohexyl-acetylacetamide melting at 74° C.
