Reaction Steps
To a solution of ethyl 2-[3-[[2,6-difluoro-3-(3-fluorophenyl)phenyl]methylamino]-2,4-difluoro-phenoxy]acetate (240 mg, 0.53 mmol, 1.0 eq) in THF (10 mL) was added a solution of aqueous NaOH (1M aqueous solution, 5 mL, 5 mmol, 9.4 eq). The reaction mixture was stirred at room temperature for 3 h. The organic solvent was removed in vacuo and the residue diluted with water and adjusted to pH 5-6 by addition of diluted HCl. The precipitate that formed was collected by filtration, washed with water and dried in vacuo to give the title compound as a solid (180 mg, 80%).
