Versuchsvorschrift

0.15 g of 2-mercaptobenzimidazole and 0.26 g of 1-(4-bromovaleroyl)-4-methylpiperidin were suspended in acetonitrile, and the suspension was added with 0.17 ml of triethylamine and refluxed for 7 hours. The reaction mixture was added with water and extracted with ethyl acetate. The organic layer was washed with water and dried over sodium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (methanol:methylene chloride=1:10) to obtain 0.07 g of the title compound as oil (yield: 21%).
