Procedure

In a manner similar to that of Example 16(a), by reaction of 1.4 g (3.4 mmol) of ethyl 3-[3-(3-hydroxy-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthyl)-4-methoxyphenyl]acrylate obtained in Example 13(f) and 760 mg (4.08 mmol) of 1-(2-chloroethyl)-piperidine hydrochloride, 1.57 g (89%) of the expected compound was obtained in the form of a colorless oil.
