A solution of 4-(7-(4-methylphenyl)-1,2,3,4-tetrahydroisoquinolin-2-ylcarbonylamino)benzyl chloride (0.2 g) and 1-methyl piperidine (0.19 ml) in dimethylformamide (5 ml) was stirred overnight at room temperature under a nitrogen atmosphere. The reaction mixture was evaporated to remove the solvent and was mixed with ethyl acetate, and the precipitate was collected by filtration. The precipitate was recrystallized from ethanol to obtain 1-methyl-1-(4-((7-(4-methylphenyl)-1,2,3,4-tetrahydroisoquinolin-2-yl)carbonylamino)benzyl)piperidinium chloride (compound 29) (0.23 g) as colorless crystals.
