Reaction Steps

To a solution of ethyl 2-[2,4-dichloro-3-[[2-fluoro-5-(3-fluorophenyl)phenyl]methylamino]phenoxy]acetate (130 mg, 0.28 mmol, 1.0 eq) in THF (20 mL), LiOH.H2O (50 mg, 1.1 mmol, 4.0 eq) was added. After the addition of water (10 mL), the mixture was heated to 60° C. overnight. The THF was then removed in vacuo and the water phase was adjusted to pH 6 by addition of 1M HCl. The precipitate was collected by filtration, washed with water and dried in vacuo to give the title compound as a solid (80 mg, 65%).
