Procedure
To a solution of 1-bromo-3,5-difluorobenzene (5.0 g, 25.9 mmol) in dimethylformamide (40 ml) was added sodiumthiomethylate (1.81 g, 25.9 mmol), and the mixture was heated to 150° C. for 10 min. The reaction mixture was brought to ambient temperature, quenched with saturated aqueous ammonium chloride (100 ml) and extracted with ethylacetate (3×100 ml). The combined organic phases was dried and concentrated in vacuo to receive the pure title compound (3.84 g). MS m/z (rel. intensity, 70 eV) 222 (M+, 100), 220 (M+, 100), 189 (49), 187 (50), 126 (75).
