Procedure

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-ethylperhydroazepine (98 mg). The mixture was stirred at room temperature for 15 hours. To the reaction mixture was added ethyl acetate (100 ml), and the resulting precipitate was filtered and recrystallized from ethyl acetate-methanol to give 1-ethyl-1-[4-[7-(4-methyl-phenyl)-3,4-dihydronaphthalene-2-carboxamido]benzyl]perhydroazepinium chloride (Compound 37) (137 mg) as colorless crystals.
