Versuchsvorschrift

To 200 ml of nitroethane, were added 12 g of acetamide, 105 of MP-500, which was also used in Example 68, and 41 g of cyclohexylbromide. They were reacted at 60° C. for 5 hours with stirring. After the reaction, the ionexchange resin was filtered off and the resulting filtrate was distilled under reduced pressure to remove the solvent and unreacted raw materials. The resulting distillation residue was recrystallized from petroleum ether, thereby obtaining 16 g of N-cyclohexylacetamide having a melting point of 108°-109° C.(yield: 57%).
