To a solution of ethyl 2-[2-fluoro-3-[[2-fluoro-5-(3-fluorophenyl)phenyl]methylamino]-4-methyl-phenoxy]acetate (260 mg, 0.61 mmol, 1.0 eq) in THF (10 mL) was added NaOH (1M aqueous solution, 5 mL, 5 mmol, 8.2 eq) at 0° C. The reaction mixture was allowed to warm to room temperature and stirred for 1 h. The organic solvent was evaporated in vacuo and the mixture that remained poured into water. The pH was adjusted to pH 4-6 with dilute HCl and the precipitate that formed was collected by filtration, washed with water and dried in vacuo to give title compound (I(i)) as a solid (200 mg, 82%).
