Reaction Conditions

Reaction Steps

In DMF (3 ml) was dissolved N-[4—(chloromethyl)-phenyl]-7-phenyl-3,4-dihydronaphthalene-2-carboxamide (160 mg), and to the mixture was added 3-ethylpyridine (146 μl). The mixture was stirred at 70° C. for 72 hours and concentrated under reduced pressure. The residue was recrystallized from ethyl acetate-methanol to give 3-ethyl-1-[4—(7-phenyl-3,4-dihydro-naphthalene-2-carboxamido)benzyl]pyridinium chloride (Compound 27) (185 mg) as colorless crystals.
