Reaction Steps

4-Benzylamino-1-[[2-(3,4,5-trimethoxyphenyl)pyridin-4-yl]methyl]piperidine (230 mg) and 4-chloromethyl-2-(3,4,5-trimethoxyphenyl)pyridine (158 mg) were condensed by the same manner as described in Example 9. Yellow oil of a free base was converted to a tetrahydrochloride which gave the title compound as yellow powder.
