実験手順

To a solution of 3-Cyano-N-(2,6-difluoro-3-hydroxy-phenyl)-5-(3-fluorophenyl)benzamide (500 mg, 2.7 mmol, 1.0 eq) in THF (30 mL) at 0° C. was added a solution of BH3 (1M in THF, 10.8 mL, 10.8 mmol, 4.0 eq) dropwise. The reaction was then heated at 50° C. for 6 h. The reaction was cooled to room temperature and quenched by addition of aqueous NH4Cl. The aqueous layer was extracted with EtOAc and the combined organic extracts dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was purified by column chromatography (petroleum ether:EtOAc, 7:1) to give the title compound as white solid (280 g, 58%).
