Reaction Steps

In DMF (3 ml) was dissolved N-[4—(chloromethyl)-phenyl]-7—(4-methylphenyl)-3,4-dihydronaphthalene-2-carboxamide (150 mg), and to the mixture was added 1-ethylpiperidine (159 μl). The mixture was stirred at room temperature for 20 hours. To the reaction mixture was added ethyl acetate (100 ml), and the resulting precipitate was filtered to give 1-ethyl-1-[4-[7—(4-methylphenyl)-3,4-dihydronaphthalene-2-carboxamido]benzyl]piperidinium chloride (Compound 34) (156 mg) as colorless crystals.
