Borane → (3-Methanesulfonylphenyl)methanol

Participants

Reaction Steps

To a solution of 3-(methylsulfonyl)benzoic acid (1.2 g, 6.0 mmol) in THF (30 mL) at 0° C., is added equimolar amounts of borane (6.0 mL of a 1.0 M solution in THF) and boron trifluoride diethyl etherate (0.8 mL, 6.0 mmol). The reaction is allowed to warm to ambient temperature overnight, and then quenched by pouring into a mixture of ice and solid NaHCO3. Following extraction with EtOAc, the organic layer is washed with brine and dried over Na2SO4. Removal of solvent affords the product as a colorless oil: MS (M+NH4)+=204.
