Procedure

Following the procedure of Example 22, but substituting dimethylformamide at 73° C. for butanol, 4-[bis(4-methoxyphenyl)methyl]piperidine and 4-(3-chloropropoxy)benzoic acid ethyl ester were reacted to give the free base of the title compound which was reacted with fumaric acid, to give the white fumarate salt (recrystallizing from methanoldiethyl ether) in 27% yield, m.p. 147.5°-148.5° C.
