To a solution of isopropyl 2-[4-fluoro-3-[[3-(3-fluorophenyl)-5-methyl-phenyl]methylamino]-2-methyl-phenoxy]acetate (200 mg, 0.46 mmol, 1.0 eq) in THF (10 mL) was added LiOH (2M aqueous solution, 4 mL, 8.0 mmol). The reaction mixture was stirred at room temperature for 2 h then the THF was removed in vacuo. The pH of the aqueous solution that remained was adjusted to pH 5 by addition of 3M HCl. The solid precipitate that formed was collected by filtration, washed with water and dried in vacuo to give the title compound as a yellow solid (150 mg, 83%).
