Participants

Reaction Steps

370 mg of intramolecularly deprotonized 2-[[[2-(2-hydroxyethoxy)-2-methylpropyl]thio]methyl]-4-methoxy-3-methyl-1-[5-(trifluoromethyl)-2-benzimdazolyl]pyridinium cation were dissolved in methanol, whereupon 100 mg of methanesulfonic acid were added thereto, the solution was concentrated and the residue was crystallized from ether/ethyl acetate. The 2-[[[2-(2-hydroxyethoxy)-2-methylpropyl]thio]methyl]-4-methoxy-3-methyl-1-[5-(trifluoromethyl)-2-benzimidazolyl]pyridinium methanesulfonate obtained exhibited a melting point of 105°-107° (decomposition).
