実験手順

A mixture comprising 2.55 g (0.017 mol) of 2-mercaptobenzimidazole, 5.09 g (0.022 mol) of 2-chloromethyl-4-(4-methoxybutoxy)pyridine, 0.84 g (0.020 mol) of 95% sodium hydroxide and 60 ml of ethanol was stirred at 40° C. for 1.5 hours. After the completion of the reaction, the reaction mixture was distilled to remove the solvent. The obtained residue was purified by silica gel column chromatography (ethyl acetate/n-hexane) to obtain 4.13 g of the title compound.
