Ethyl Acetate → [2-(Propan-2-ylsulfanyl)pyridin-3-yl]methanol

Participants

Reaction Steps

2-Isopropylsulfanyl-nicotinic acid obtained in Step A was dissolved in THF (50 mL), and the solution was cooled to 0˜5° C. LAH (3.06 g, 80.55 mmol) was added thereto slowly, and the mixture was stirred at 0˜5° C. for 30 minutes and then at room temperature for 2 hours. After the termination of the reaction, saturated sodium sulfate aqueous solution was added thereto and the mixture was stirred for 30 minutes. After the addition of EtOAc, solid material was removed by using cellite. The organic layer was dried with MgSO4, filtrated and concentrated under reduced pressure. The residue was purified by column chromatography (eluent, EtOAc/Hex=1/3) to obtain the title compound (3.94 g, 67%).
