Versuchsvorschrift

(E)-4-Methylpent-2-enoic acid (46 mg, 0.4 mmol), HBTU (152 mg, 0.4 mmol) and triethylamine (82 μl, 0.6 mmol) were dissolved in a 1:1 mixture of anhydrous DMF and anhydrous acetonitrile (2 ml), after 20 minutes N-(5-ethyl-6-methyl-pyrimidin-4-yl)ethane-1,2-diamine hydrochloride (40 mg, 0.185 mmol) was added. The mixture was stirred at room temperature for 2 hours and left to stand at room temperature overnight. The reaction mixture was diluted with ethyl acetate, washed with water, saturated sodium bicarbonate solution and brine, dried over magnesium sulfate and evaporated to dryness under reduced pressure. The residue was purified by preparative HPLC (gradient of water containing 0.1% NH3 and acetonitrile) to yield 9 mg (0.033 mmol, 18%).
