Procedure

To a solution of N-(4-chloromethylphenyl)-2-(4-methylphenyl)-6,7-dihydro-5H-benzocycloheptene-8-carboxamide (9.38 g, 23.3 mmol) in DMF (50 ml) was dropwise added a solution of N,N-dimethyl-N-tetrahydropyran-4-ylamine (4.5 g, 35.0 mmol) in DMF (50 ml). Under nitrogen atmosphere, the mixture was stirred for 23 hours. The solvent was evaporated to give powder, which was washed with acetone and dried. The resulting colorless powder was recrystallized from ethanol to give N,N-dimethyl-N-(4-(((2-(4-methylphenyl)-6,7-dihydro-5H-benzocyclohepten-8-yl)carbonyl)amino)benzyl)-N-(4-tetrahydropyranyl)ammonium chloride (Compound 1) (10.6 g, 86%) as colorless powder.
