실험 절차

1-(2,6-Dimethoxy-4-pyridyl)piperazine (30 mg, 0.13 mmol) was dissolved in anhydrous dichloromethane (2 ml) together with (E)-4,4,5,5,5-pentafluoropent-2-enoic acid (35 mg, 0.18 mmol), triethylamine (31 mg, 44 μl, 0.32 mmol), HBTU (74 mg, 0.15 mmol) and stirred at room temperature for two hours. The mixture was evaporated to dryness under reduced pressure and the residue was purified by preparative HPLC (gradient of water containing 0.1% NH3 and acetonitrile) to yield 9 mg of a solid (0.023 mmol, 15%).
