Participants

Procedure

Using 2.3 g of N-(trans-4-methylcyclohexyl)-5-(4-hydroxy-3-methoxyphenyl)valeramide (Example 118), 100 ml of methylisobutylketone, 5 g of potassium carbonate, and 4 ml of 1-bromo-2-chloroethane, a reaction similar to that conducted in Example 106 was carried out. As a result, 2.1 g of N-(trans-4-methylcyclohexyl)-5-[4-(2-chloroethoxy)-3-methoxyphenyl]valeramide (a compound of the present invention) was obtained as a pale yellow oil, which had the following physiochemical properties:
