Versuchsvorschrift

To the solution of (2S)-2-methyl-5-(trifluoromethyl)piperazine (4-20) was added DMA (1.76 ml), DIEA (0.614 ml, 3.52 mmol) followed by 7-(bromomethyl)-4-(4-fluorophenyl)quinoline-2-carbonitrile (300 mg, 0.879 mmol). The reaction was heated to 50° C. for 4 hours. The reaction was diluted with EtOAc and then washed with H2O, brine, dried (MgSO4) and concentrated. The residue was purified by column chromatography on silica gel eluting with hexanes to EtOAc to provide 4-(4-fluorophenyl)-7-(((2S)-2-methyl-5-(trifluoromethyl)piperazin-1-yl)methyl)quinoline-2-carbonitrile as a colorless solid. LRMS m/z (M+H)+ 429.2 found, 429.4 required.
