Reaction Steps
Ethyl 2-[3-[[3-cyano-5-(3-fluorophenyl)phenyl]methylamino]-2,4-difluoro-phenoxy]acetate (300 mg, 0.68 mmol, 1.0 eq) was dissolved in THF (20 mL). Water (10 mL) and LiOH.H2O (110 mg, 2.7 mmol, 4 eq) were added and the solution heated at 40° C. overnight. The THF was removed in vacuo and the aqueous phase acidified to pH 6 by addition of diluted HCl. The precipitate that formed was collected by filtration, washed with water and dried to give the title compound as a white solid (70 mg, 25%).
