Versuchsvorschrift

(E)-4-Methylhex-2-enoic acid (26 mg, 0.2 mmol) was dissolved in DMF (0.5 ml) together with diisopropylethylamine (35 μl), HATU was added (76 mg, 0.2 mmol) and the mixture was stirred at room temperature for 15 minutes. 4-piperazin-1-yl-7-(trifluoromethyl)quinoline (56 mg, 0.2 mmol) was dissolved in DMF (0.5 ml) together with diisopropylethylamine (35 μl), the two solutions were combined and stirred at room temperature overnight. The mixture was evaporated to dryness under reduced pressure and the residue was purified by preparative HPLC (gradient of water containing 0.1% NH3 and acetonitrile) to yield 62.6 mg (0.16 mmol, 80%). MS (APCI) m/z=391.9 [M+1]+.
