The reaction solution was cooled to room temperature, the reaction solution was filtered, and the solvent was removed from the filtrate by distillation under the reduced pressure. The residue was purified by thin layer chromatography using chloroform-methanol to give 6-methylsulfanyl-[2,3′]bipyridin-3-ol (13 mg, yield 45%).
