실험 절차
To a solution of 3-bromo-pyridine-4-carbaldehyde (0.500 g, 2.68 mmol) in MeOH (5 mL) at 0° C. is added sodium borohydride (0.122 g, 3.22 mmol). The mixture is stirred at room temperature for 1 h followed by removal of the solvent in vacuo. The residue is redissolved in DCM and washed with water twice. The organic layer is dried over sodium sulfate and concentrated in vacuo to afford (3-bromo-pyridin-4-yl)-methanol as a yellow oil. MS (ESI) m/z 189.9 (M+H)+
