Using 1.7 g of 2-chloro-4-(2-tetrahydropyranyloxy)cinnamic acid, 1.4 ml of diethyl chlorophosphate, 1.4 ml of triethylamine, 60 ml of methylene chloride, 1.4 ml of N-(2-dimethylaminoethyl)-trans-4-methylcyclohexylamine (Example 78), and 0.25 g of 4-dimethylaminopyridine, a reaction similar to that performed in Example 81 was carried out. As a result, 3.01 g of N-(2-dimethylaminoethyl)-N-(trans-4-methylcyclohexyl)-2-chloro-4-(2-tetrahydropyranyloxy)cinnamamide (a compound of the present invention) was obtained as white crystal, which had the following physiochemical properties:
