Reaction Steps
To a stirred solution of ethyl 2-[2,4-difluoro-3-[[2-fluoro-3-(3-fluorophenyl)-5-hydroxy-phenyl]methylamino]phenoxy]acetate (120 mg, 0.27 mmol, 1.0 eq) in THF (6 mL) at room temperature was added NaOH (1M aqueous solution, 3 mL, 3.0 mmol, 11.1 eq). The reaction was stirred at room temperature for 2 h. The solvent was then removed in vacuo and the solid obtained taken up in water and the aqueous layer acidified to pH 3-6 by addition of 1M HCl. The aqueous layer was extracted with EtOAc and the combined organic extracts were washed with water and brine, dried (Na2SO4) and evaporated in vacuo to give the title compound (I(f)) as a gummy solid (105 mg, 94%).
