Reaction Steps

467.5 mg of intramolecularly deprotonized 2-[[(2-acetoxy-2-methylpropyl)thio]methyl]-4-methoxy-3 methyl-1-[5-(trifluoromethyl)-2-benzimidazolyl]pyridinium cation were dissolved in 5 ml of methanol, whereupon 96 mg of methanesulfonic acid were added thereto, the solution was concentrated, the residue was dissolved several times in ethyl acetate and the solution was again concentrated each time. The resinous residue was dried in a high vacuum, whereby 2-[[(2-acetoxy-2-methylpropyl)thio]methyl]-4-methoxy-3-methyl-1-[5-(trifluoromethyl)-2-benzimidazolyl]pyridinium methanesulfonate (1:1) was obtained as a foam. The microanalysis showed the following values:
