Reaction Steps

60 mg of intramolecularly deprotonized 4-methoxy 3-methyl-2-[[(2-methylpropenyl)thio]methyl]-1-[5-(trifluoromethyl)-2-benzimidazolyl]pyridinium cation were dissolved in methylene chloride, whereupon 0.5 ml of 4.7N methanolic hydrochloric acid was added thereto, the solution was concentrated and the residue was crystallized from ethyl acetate/ether. The 4-methoxy-3-methyl-2-[[(2-methylpropenyl)thio]methyl]-1-[5-(trifluoromethyl)-2-benzimidazolyl]pyridinium chloride obtained exhibited a melting point of 142°-144°.
