Versuchsvorschrift

To 10 ml of ethyl acetate were added 0.50 g of 3,4,5-trifluorobenzoyl chloride, 0.32 g of cyclohexylmethylamine and 0.50 g of triethylamine and the mixture obtained was stirred at room temperature for 3 hours. The reaction mixture was filtered through Celite. The filtrate was concentrated under reduced pressure. Crystals obtained were washed with a mixture of hexane and MTBE to obtain 0.70 g of N-cyclohexylmethyl-3,4,5-trifluorobenzamide. N-cyclohexylmethyl-3,4,5-trifluorobenzamide:
