실험 절차

To a solution of 2-(thien-2-yl)-5-pyridinecarboxylic acid (0.333 g, 1.60 mmol) in THF (5 mL) at 0° C. is added 1.0M lithium aluminum hydride in diethyl ether (1.60 mL, 1.60 mmol) over 10 minutes. The reaction is allowed to stir at ambient temperature for 3 hours, cooled to 0° C., and water (0.10 mL), 4N aq. NaOH (0.10 mL), and water (0.30 mL) are added sequentially. The reaction is filtered through a pad of Celite and the filtrate is evaporated in vacuo. The residue is purified by chromatography to afford the title compound.
