実験手順

To a stirred solution of (R)-1-(5-bromopyridin-3-yl)ethyl acetate (1.21 g, 4.96 mmol, synthesis described herein) in MeOH (20 mL), was added K2CO3 (1.37 g, 9.92 mmol) and the reaction was stirred for 1 h. All the solvent was removed, the residue was dissolved in cold water and extracted with EtOAc (2×50 mL), to provide 1.0 g of crude (R)-1-(5-bromopyridin-3-yl)ethanol.
