Reaction Steps

Using 2.9 g of (4-acetoxy-3-methoxyphenyl)acetic acid derived from homovanillic acid by the acetylation thereof, 2.8 ml of diethyl chlorophosphate, 3.9 ml of triethylamine, 60 ml of methylene chloride, 2 g of trans-4-methylcyclohexylammmonium chloride, 0.6 g of 4-dimethylaminopyridine, 100 ml of methanol, and 5 g of potassium carbonate, a reaction similar to that conducted in Example 121 was carried out. The product obtained was recrystallized from methylene chloride/hexane, yielding 1.5 g of N-(trans-4-methylcyclohexyl)-2-(4-hydroxy-3-methoxyphenyl)acetamide (a compound of the present invention) as pale yellowish white crystal, which had the following physiochemical properties:
