1-(3-Pyridyl)ethanol (8.9 g), tributyrin (24.0 g) and an enzyme (Lipase CES made by Amano Seiyaku K. K.) (3.6 g) were agitated at 37° C. for 190 hours, followed by filtering off the enzyme and subjecting the filtrate to silica gel column chromatography using toluene as solvent to obtain (S)-1-(3-pyridyl)ethanol (3.0 g). According to a high-speed liquid chromatography using an optical resolution column (CHIRAL CEL OB, trademark of product made by Daicel Co., Ltd.), its optical purity was 80% ee or higher.
