Procedure
The 3-(4-bromo-2,6-dimethylphenoxymethyl)-1-methylpiperidine was treated with 1N hydrochloric acid in ether, and the precipitated salt was recrystallized from acetonitrile/tert-butyl methyl ether to yield 3-(4-bromo-2,6-dimethylphenoxymethyl)-1-methylpiperidine hydrochloride, m.p. 180.9-183.5° C.
