Procedure
4-Propargylamino-1-[[2-(3,4,5-trimethoxyphenyl]pyridin-4-yl]methyl]piperidine (227 mg) and 4-chloromethyl-2-(3,4,5-trimethoxyphenyl)pyridine (226 mg) were condensed in the same manner as described in Example 9. The title compound was obtained as yellow powder after converting a free base to a tetrahydrochloride. Yield: 128 mg (23%). 1H-NMR (400 MHz, measured as a free base, CDCl3) δ: 1.48-2.40 (m, 7H), 2.72 (br, 1H), 3.02 (br, 2H), 3.39 (s, 2H), 3.64 (br, 2H), 3.84 (s, 2H), 3.91 (s, 6H), 3.98 (s, 6H), 3.99 (s, 6H), 7.22-7.29 (m, 6H), 7.66 (br, 2H), 8.60 (d, 1H, J=4.9 Hz), 8.62 (d, 1H, J=4.9 Hz).
