実験手順

To a solution of 3-chloro-4-(methoxycarbonyl)benzoic acid (400 mg, 1.9 mmol) in anhydrous THF (15 mL) was added Borane methyl sulfide complex (10 M, 0.56 mL, 5.6 mmol). The resulting solution was heated at 76° C. for 6 hours. After being cooled, the mixture was slowly poured into water (40 mL) at −10° C., then followed a standard aqueous/EtOAc workup procedure to give crude product (350 mg, yield 94%).
