실험 절차

To a refluxing solution of 50 mg of (2-hydroxy-5-nitro-phenyl)-[4-(4-trifluoromethyl-phenyl)-piperazin-1-yl]-methanone in acetone (2 mL) containing potassium carbonate (35 mg) was added 2,2,3,3,3-pentafluoropropyl trifluoromethanesulfonate (54 mg) over 10 min. The reaction mixture was refluxed for 20 hours before being concentrated in vacuo and purified by column chromatography (SiO2, CH2Cl2/MeOH) to yield the title compound as a colorless solid (66 mg). MS (m/e): 569.0 (M+H+, 100%).
