Procedure

A mixture comprising 0.03 g (0.18 mmol) of 2-mercapto-1H-benzimidazole, 0.06 g (0.21 mmol) of 2-chloromethyl-3-methyl-4-(2-succinimidoethoxy)pyridine, 0.03 g (0.21 mmol) of potassium carbonate and 10 ml of methyl ethyl ketone was heated under reflux in a nitrogen atmosphere for 3 hours, cooled and filtered. The filtrate was concentrated and dried in a vacuum, followed by the addition of water. The obtained mixture was extracted with 50 ml of chloroform thrice. The extract was dried over magnesium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography to obtain 0.08 g of 2-[{3-methyl-4-(2-succinimidoethoxy)pyridine-2-yl}methylthio]-1H-benzimidazole as a white crystal.
