Versuchsvorschrift

To a solution of 3-bromo-2-fluorobenzotrifluoride (1.0 g, 4.1 mmol) in methanol (5 ml) was added a solution of sodium methoxide in methanol (30%, 0.73 ml, 4.1 mmol). The mixture was heated under microwave radiation to 150° C. for 10 min. The reaction mixture was poured into water and extracted with ethylacetate (3×50 ml). The combined organic phases was dried (MgSO4), filtered and evaporated to dryness to give the title compound (0.89 g). MS m/z (rel. intensity, 70 eV) 256 (M+, 87), 254 (M+, 89), 239 (26), 211 (24), 132 (bp).
