Benzoyl chloride → N-Cyclohexylbenzamide

Participants

Reaction Steps

18 g of cyclohexylamine was dissolved in 150 ml of benzene. To the resulting solution was very slowly added 20 g of benzoyl chloride with stirring at temperatures below 40° C. White crystals separated from the mixture, generating white smoke. The mixture was stirred for one hour and was then made alkaline by addition of pyridine thereto. The product was filtered with suction. Crude crystals melting at 142° C. to 144° C. were recrystallized from a mixture of methanol and ethanol (1:1 in volume), from which white needles melting at 144° C. to 145° C. separated. The yield was 84%.
