A solution of 4-(7-(4-methylphenyl)-1,2,3,4-tetrahydroisoquinolin-2-ylcarbonylamino)benzyl chloride (0.2 g) and 1-ethylpiperidine (0.21 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 to obtain 1-ethyl-1-(4-((7-(4-methylphenyl)-1,2,3,4-tetrahydroisoquinolin-2-yl)carbonylamino)benzyl)piperidinium chloride (compound 30) (0.24 g) as a light red, amorphous substance.
