Participants

Reaction Steps

0.415 g of the compound obtained in Example 14b and 0.15 g of 2-mercaptobenzimidazole were refluxed for 5 hours in 10 ml of acetonitrile solvent containing 0.15 g of triethylamine. After cooling to room temperature, the reaction mixture was added with water and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate:hexane) to obtain 0.28 g of the title compound (yield: 71%).
