Reaction Steps
To a stirring solution of ethyl 2-(6-bromo-3-(difluoromethoxy)-2-methoxyphenoxy)acetate (300 mg, 0.845 mmol) in tetrahydrofuran was added lithium hydroxide in water and the reaction mixture was stirred at RT for 1 h. The reaction mixture was concentrated under reduced pressure and the obtained residue was acidified to pH 2 and then extracted with ethyl acetate. The combined ethyl acetate layers were dried over sodium sulphate and concentrated under reduced pressure to afford 2-(6-Bromo-3-(difluoromethoxy)-2-methoxyphenoxy)acetic acid as a solid (180 mg, 66%).
