To a solution of 5-(3-fluorophenyl)-N-(3-hydroxy-2,6-dimethyl-phenyl)-2-methoxy-3-methyl-benzamide (270 mg, 0.71 mmol, 1.0 eq) in THF (5 mL) at 0° C. under N2 was added a solution of BH3 (1M in THF, 1.07 mL, 1.07 mmol, 1.5 eq) dropwise. The reaction mixture was heated at 60° C. for 4 h, then cooled and quenched with water. The aqueous layer was extracted with EtOAc and the combined organic extracts were washed with water and brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was purified by column chromatography (petroleum ether:EtOAc 30:1 to 20:1) to give the title compound as a yellow oil (115 mg, 44%)
