Reaction Steps
A solution of 3-fluoro-2-(trifluoromethyl)benzonitrile (1.2 g, 6.3 mmol) and piperazine (0.72 g, 8.4 mmol) in acetonitrile (6 ml) was heated under microwave radiation at 150° C. for 15 minutes. The reaction mixture was poured into water (50 ml) and the aqueous phase was extracted with ethylacetate (3×50 ml). The combined organic phases was dried (MgSO4), filtered and evaporated to dryness. Purification by flash column chromatography (ethylacetate/methanol, 1:1) gave the title compound: 1.1 g. MS m/z (rel. intensity, 70 eV) 255 (M+, 16), 214 (11), 213 (bp), 171 (8), 151 (7).
