Versuchsvorschrift

To 4-[(1S,4S)-2,5-diazabicyclo[2.2.1]heptan-5-yl]quinoline hydrochloride (26.2 mg, 0.1 mmol), dissolved in 0.5 ml anhydrous dichloromethane, polymer-supported diisopropylethylamine (80 mg, 3-4 mmol/g) was added followed by (E)-hex-2-enoyl chloride (19.9 mg, 0.15 mmol) dissolved in anhydrous dichloromethane (1 ml). The mixture was shaken at room temperature for 20 minutes, filtered and the filtrate evaporated to dryness under reduced pressure. The raw product was purified by preparative HPLC (gradient of water containing 0.1% ammonia and acetonitrile) to yield 9 mg of a solid (0.028 mmol, 28%).
