Reaktionsschritte

A mixture of 2-trifluoromethyl-4-nitrophenol (73.4 g, 0.354 mol), ethyl bromoacetate (65.2 g, 0.39 mol), potassium carbonate (58.7 g, 0.425 mol) and 2-butanone (400 mL) was refluxed under stirring for 10 h. The solid was filtered off, the filtrate was evaporated and the residue was fractionated yielding 97.8 g (95%) of 2-trifluromethyl-4-nitrophenoxyacetic acid ethyl ester, b.p. 126° C./40 Pa.
