Reaction Steps

To a solution of 2,4-dichloro-6-trifluoromethylphenylacetic acid methyl ester (0.93 mmol) in 3 mL THF was added an aq. solution of LiOH (2.8 mmol, 2M). After stirring at RT for 3 days, water was added and the mixture was extracted twice with EtOAc. The aqueous phase was acidified to pH 2-3 with 1N HCl solution and extracted 3 times with EtOAc. The combined organic layers were dried over MgSO4 and concentrated in vacuo to give the desired product as white solid.
