実験手順

2-((3-Methyl-4-(2-morpholinoethylthio)-2-pyridyl)methylthio)- 1H-benzimidazole (10 g) was reacted with 1.1 equivalents of ethyl chlorocarbonate in dimethylformamide in the presence of 1.1 equivalents of sodium hydride at room temperature. After the completion of the reaction, the solvent was distilled away and water was added to the residue, followed by extraction with chloroform. The chloroform layer was dried over anhydrous magnesium sulfate and the solvent was distilled away to give 11 g of ethyl 2-((3-methyl-4-(2-morpholinoethylthio)-2-pyridyl)-methylthio)-1H-benzimidazole-1-carboxylate as crystals, melting point 145°-147° C.
