Versuchsvorschrift

(E)-4-Hydroxypent-2-enoic acid (67 mg, 0.52 mmol) was dissolved in anhydrous DMF (2.5 ml), DCC (107.5, 0.52 mmol) and HOAt (106.7 mg, 0.79 mmol) were added and the mixture was stirred at room temperature for 15 minutes. 2-Methyl-4-piperazin-1-yl-quinoline (118.2 mg, 0.52 mmol) was added and stirring was continued for 90 minutes. The mixture was evaporated to dryness, taken up in a mixture of acetonitrile and methanol and filtered. The filtrate was evaporated to dryness again and purified by preparative HPLC (gradient of water containing 0.1% TFA and acetonitrile). 110 mg were obtained (0.33 mmol, 65%). MS (ES): m/z=326.1 [M+1]+.
