実験手順
2-((3-Methyl-4-(2-benzylaminoethylthio)pyridin-2-yl)-methylthio)-1H-benzimidazole (2 g) was dissolved in dimethylformamide and reacted with methyl chloroacetate (0.45 ml) in the presence of potassium carbonate (0.71 g) at 50°-60° C. After the completion of the reaction, the dimethylformamide was distilled away and the residue was extracted with ethyl acetate. The ethyl acetate layer was dried over anhydrous magnesium sulfate and the solvent was distilled away to give an oily product. The oily product was purified by column chromatography to give 2-((3-methyl-4-(2-(N-benzyl-N-methoxycarbonylmethylamino)ethylthio)-2-pyridyl)methylthio)-1H-benzimidazole.
