Using 3.4 g of 3,4-diacetoxycinnamic acid derived from caffeic acid by the acetylation thereof, 2.8 ml of diethyl chlorophosphate, 3.9 ml of triethylamine, 2 g of trans-4-methylcyclohexylammmonium chloride, 60 ml of methylene chloride, and 0.6 g of 4-dimethylaminopyridine, a reaction similar to that conducted in Example 81 was carried out. The product obtained was recrystallized from methylene chloride/hexane, yielding 3.19 g of N-(trans-4-methylcyclohexyl)-3,4-diacetoxycinnamamide (a compound of the present invention) as white crystal, which had the following physiochemical properties:
