1-(4-Quinolyl)piperazin-2-one (23 mg, 0.1 mmol) was dissolved in dichloromethane (1 ml), triethylamine was added (21 μl, 0.15 mmol) followed by a solution of (E)-4-methylpent-2-enoyl chloride in 0.5 ml dichloromethane. The mixture was shaken briefly, washed with 5% sodium bicarbonate solution (2×), water and evaporated to dryness. The raw product was purified by preparative HPLC (gradient of water containing 0.1% ammonia and acetonitrile). 14.4 mg of a solid residue were obtained (0.044 mmol, 44%).
