Procedure

In DMF (3 ml) was dissolved (E)-N-[4-(chloromethyl)phenyl]-3- (4-methylphenyl)cinnamamide (200 mg), and to the solution were added 2-(3,4-dimethoxyphenyl)ethylmethylamine (132 μl) and potassium carbonate (382 mg). The mixture was stirred at room temperature for 12 hours, and to the mixture was added water (50 ml). The mixture was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution, dried with anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was separated and purified with column chromatography (ethyl acetate) to give colorless amorphous, which was dissolved in ethyl acetate (50 ml), and to the mixture was added 4N hydrochloric acid ethyl acetate solution (0.5 ml). The resulting precipitate was filtered and recrystallized from ethyl acetate-methanol to give (E)-N-[4-[N-[2-(3,4-dimethoxyphenyl)ethyl]-N-methylaminomethyl]phenyl]-3-(4-methylphenyl)cinnamamide hydrochloride (Compound 63) (245 mg) as colorless crystals.
