Procedure
A mixture of 4-trifluoromethyl-phenol (10.000 g; 61.687 mmol), potassium carbonate (9.377 g; 67.856 mmol), and methyl bromoacetate (5.67 ml; 61.687 mmol) in acetone (250 ml) was heated at reflux for 1 h30. Filtration, concentration to dryness under reduced pressure, and purification by FC (DCM) afforded (4-trifluoromethyl-phenoxy)-acetic acid methyl ester as a colorless oil (14.100 g; 98%). LC-MS: tR=0.95 min.; [M+H]+: no ionisation.
