Participants

Reaction Steps

Using 5.9 g of 3-acetoxy-4-methoxycinnamic acid derived from isoferulic acid by the acetylation thereof, 4.34 ml of diethyl chlorophosphate, 8.35 ml of triethylamine, 500 ml of methylene chloride, 3.74 g of trans-4-methylcyclohexylammonium chloride, and 0.18 g of 4-dimethylaminopyridine, a reaction similar to that conducted in Example 104 was carried out. As a result, 6.3 g of N-(trans-4-methylcyclohexyl)-3-acetoxy-4-methoxycinnamamide (a compound of the present invention) was obtained as white crystal, which had the following physiochemical properties: Proton nuclear magnetic resonance spectrum (δ ppm in CDCl3):
