Методика

To a solution of N-Boc-Piperazine (0.65 g) in DMA (20 mL) was slowly added a solution of 2,3,4-trifluorobenzonitrile (0.49 g) in DMA (10 mL). The reaction mixture was stirred for 2 hours at 80° C. After such time the solvent was removed in vacuo and purified by column chromatography (SiO2) to yield the title compound as white solid (0.76 g).
