To a stirred solution of (3-carboxymethylphenyl)acetic acid (1.0 g, 5.15 mmol) in THF (100 mL) was added slowly borane dimethyl sulfide (2.3 mL, 30.9 mmol). The resulting solution was stirred overnight (˜18 hours) and then quenched by slowly adding 1N HCl (100 mL). The mixture was then extracted using EtOAc (3×100 mL) and the combined organic layers were washed with saturated NaCl (100 mL), dried over magnesium sulfate, filtered and concentrated under vacuum to provide 750 mg of the title intermediate (87% yield), which was used without further purification.
