Reaction Steps

To a solution of N-(2,6-difluoro-3-hydroxy-phenyl)-2-fluoro-3-(3-fluorophenyl)-5-methyl-benzamide (130 mg, 0.30 mmol, 1.0 eq) in THF (25 mL) was added dropwise a solution of borane (1M in THF, 1.2 mL, 1.2 mmol, 4 eq) under N2. The reaction was heated at 60° C. overnight. TLC showed the reaction was not complete so further borane (1 M in THF, 1.0 mL, 1 mmol) was added and heating continued at 60° C. for 2 h. The mixture was poured into water and extracted with EtOAc and the combined organic extracts washed with water and brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was purified by chromatography (EtOAc:petroleum ether, 0:1 to 1:4) to give the title compound as an oil (100 mg, 80%).
