5-Methoxy-7-piperazin-1-yl-pyrazolo[1,5-a]pyrimidine (23.3 mg, 0.1 mmol) was dissolved in anhydrous dichloromethane (1 ml), TEA (17.4 μl, 1.25 mmol) followed by (E)-pent-2-enoyl chloride (14.8 mg, 0.125 mmol) were added, the mixture was shaken for 10 minutes, diluted with dichloromethane, washed with 10% sodium bicarbonate solution, water and the organic phase was evaporated to dryness under reduced pressure. The residue was purified by preparative HPLC (gradient of water containing 0.1% NH3 and acetonitrile) to yield 16.1 mg of a solid (0.05 mmol, 51%).
