Participants

Reaction Steps

Using 3.4 g of 3,4-diacetoxycinnamic acid derived from caffeic acid by the acetylation thereof, 2.8 ml of diethyl chlorophosphate, 2.7 ml of triethylamine, 100 ml of methylene chloride, 3.0 ml of N-(2-dimethylaminoethyl)-trans-4-methylcyclohexylamine (Example 78), and 0.5 g of 4-dimethylaminopyridine, a reaction similar to that conducted in Example 81 was carried out. As a result, 0.68 g of N-(2-dimethylaminoethyl)-N-(trans-4-methylcyclohexyl)-3,4-diacetoxycinnamamide (a compound of the present invention) was obtained as pale yellow crystal, which had the following physiochemical properties:
