2.5 ml of an 8.4N hydrochloric acid/ethanol solution are added to a solution, cooled in an ice bath, of 7.4 g (20.3 mmol) of 4,5-dichloro-2-methyl-1-[4-(4-phenyl-1,2,3,6-tetrahydro-1-pyridyl)butyl]-1H-imidazole in 15 ml of absolute ethanol. After a few minutes, a precipitate appears which is filtered, washed with cold ethanol and dried, 7.7 g (19.2 mmol) of 4,5-dichloro-2-methyl-1-[4-(4-phenyl-1,2,3,6-tetrahydro-1-pyridyl)-butyl]-1H-imidazole hydrochloride being obtained.
