1,1,1,3,3,3-Hexafluoro-2-{6-[4-(2-hydroxyethyl)piperazin-1-yl]-4-propylpyridin-3-yl}propan-2-ol (208 mg, 0.501 mol) was dissolved in dichloromethane (2.5 mL), added pyridine (121 μL, 1.50 mmol) and anhydrous acetic acid (142 μL, 1.50 mmol) under ice-cold conditions, and the mixture was stirred at room temperature for 3 hours. The reaction solution was added methanol, stirred at room temperature for 0.5 hours. The reaction solution was concentrated in vacuo, extracted with chloroform. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. The title compound (247 mg) was obtained as a red-brown oil.
