실험 절차

To a solution of 2-phenyl-5-carboxypyridine (520 mg, 2.61 mmol) in tetrahydrofuran (10 mL) at 0° C. was added 1.0M lithium aluminum hydride in tetrahydrofuran (2.61 mL, 2.61 mmol) over 10 minutes. The reaction was allowed to stir at ambient temperature for 16 hours, cooled to 0° C., and quenched by dropwise addition of water (0.20 mL), 4N aq. NaOH (0.20 mL), and water (0.60 mL). The reaction was filtered through a pad of Celite and the filtrate evaporated in vacuo. The residue was chromatographed (silica gel, 0-5% MeOH in CH2Cl2) to afford the title compound.
