Sodium Hydroxide → 2-[3-(Trifluoromethyl)phenoxy]acetic acid

Participants

Reaction Steps

A solution of (3-trifluoromethyl-phenoxy)-acetic acid methyl ester (7.220 g; 30.832 mmol) in MeOH (100 ml) was treated with aq. 1N NaOH (46.3 ml; 1.5 eq.), and the resulting mixture was further stirred at rt for 20 min. MeOH was then removed under reduced pressure, water (100 ml) was added followed by aq. 1N HCl (75 ml). Filtration of the precipitated solid, and drying under HV afforded (3-trifluoromethyl-phenoxy)-acetic acid as a colorless solid (6.020 g; 89%). LC-MS: tR=0.85 min.; [M+H]+: no ionisation.
