To a 1M solution of lithium aluminum hydride in THF (57 mL) at 0° C. is added a solution of 2-fluoro-5-methylbenzoic acid (8.0 g, 52 mmol) in 160 mL of ether drop-wise. The reaction is then heated at reflux for 1.5 hr. The reaction is then cooled to 0° C. and is quenched with H2O (4 mL), aqueous 40% NaOH (4 mL) and H2O (4 mL). The resultant slurry is then filtered through celite and MgSO4. The filtrate is then concentrated and purified by silica gel flash column chromatography to provide the title compound.
