Reaction Steps

450 mg of intramolecularly deprotonized 2-[[(2-ethoxy-2-methylpropyl)thio]methyl]-4-methoxy-3-methyl-1-[5-(trifluoromethyl)-2-benzimidazolyl]pyridinium cation were dissolved in methylene chloride, whereupon 2 ml of 4.7N methanolic hydrochloric acid were added thereto, the solution was concentrated and the residue was crystallized from ether. The 2-[[(2-ethoxy-2-methylpropyl)thio]methyl]-4-methoxy-3-methyl-1-[5-(trifluoromethyl)-2-benzimidazolyl]pyridinium chloride obtained exhibited a melting point of 119°-120°.
