Reaction Steps

Using 4g of 4-(4-benzyloxy-3-methoxyphenyl)-1,3-butadiene-1-carboxylic acid disclosed in the literature [R. Backstrom, E. Honkanen, A. Pippuri, P. Kairisalo, J. Pystynen, K. Heinola, E. Nissinen, I. Linden, P. T. Mannisto, S. Kaakkola, and P. Pohto, J. Med. Chem., 32, 841-848 (1989)], 3 ml of diethyl chlorophosphate, 3.5 ml of triethylamine, 150 ml of methylene chloride, 4 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, 3.81 g of N-(2-dimethylaminoethyl)-N-(trans-4-methylcyclohexyl)-4-(4-benzyloxy-3-methoxyphenyl)-1,3-butadiene-1-carboxamide (a compound of the present invention) was obtained as a pale yellow oil, which had following physiochemical properties:
