Procedure
4-Hydroxybenzoic acid (2.045 mmol, 0.282 g), 1,1,1,3,3,3-hexafluoro-2-(4-(piperazin-1-ylmethyl)phenyl)propan-2-ol (2.045 mmol, 0.7 g) and triethylamine (6.14 mmol, 0.853 mL, 0.621 g) were combined and stirred at room temperature in dichloromethane (5 mL). 1-Propanephosphonic acid cyclic anhydride (3.07 mmol, 1.826 mL, 1.952 g; 50% solution in ethyl acetate) was added and the reaction stirred for 2 hours. The reaction mixture was washed with saturated sodium bicarbonate solution and the organic layer dried over magnesium sulphate and concentrated under vacuum. The residue was dissolved in dichloromethane with a few drops of methanol and purified by column chromatography (dichloromethane—6% methanol in dichloromethane) to afford the title compound (90 mg). MS (ESI) m/z 463.0 [M+H]+
