Participants

Reaction Steps

To a solution of isopropyl 2-[3-[[5-(3-fluorophenyl)-2,3-dimethyl-phenyl]methylamino]-2,4-dimethyl-phenoxy]acetate (80 mg, 0.17 mmol, 1.0 eq) in a mixture of THF (5 mL) and MeOH (5 mL) was added NaOH (2M aqueous solution, 3 mL, 6.0 mmol) at 0° C. The reaction mixture was allowed to warm to room temperature and stirred for 2 h. The organic solvent was removed in vacuo and the remaining aqueous solution diluted with water and acidified to pH 4-6 with diluted HCl. The solid precipitate that formed was collected by filtration, washed with water and dried in vacuo to give the title compound as a white solid (20 mg, 27%).
