Participants

Reaction Steps

Using 4g of 4-(4-benzyloxy-3-methoxyphenyl)-l,3-butadiene-1-carboxylic acid, 3 ml of diethyl chlorophosphate, 3.5 ml of triethylamine, 150 ml of methylene chloride, 2.2 g of trans-4-methylcyclohexylammonium chloride, and 0.5 g of -dimethylaminopyridine, a reaction similar to that conducted in Example 81 was carried out. As a result, 3.62 g of N-(trans-4-methylcyclohexyl)-4-(4-benzyloxy-3-methoxyphenyl)-1,3-butadiene-l-carboxamide (a compound of the present invention) was obtained as a pale yellowhish brown oil, which had the following physiochemical properties:
