Reaction Steps

To a solution of 5-bromo-N-(2,6-difluoro-3-hydroxy-phenyl)-2-fluoro-benzamide (5.78 g, 7.1 mmol, 1.0 eq) in THF (100 mL) at 0° C. under N2 was added a solution of BH3 (1M in THF, 83.5 mL, 83.5 mmol, 5.0 eq) dropwise. The reaction mixture was heated at 60° C. overnight then cooled to room temperature 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 was purified by column chromatography (petroleum ether:EtOAc, 30:1 to 20:1) to give the title compound as a brown oil (5.26 g, 94%).
