2-(4-(Bromomethyl)phenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol (4.61 mmol, 1.553 g), potassium carbonate (13.82 mmol, 1.910 g) and methyl piperazine-2-carboxylate dihydrochloride (4.61 mmol, 1 g) were combined and stirred at room temperature overnight in acetonitrile (25 mL). The reaction mixture was filtered and the solid washed with ethyl acetate. The organic was concentrated under reduced pressure. The resulting residue was purified by silica column chromatography (eluant dichloromethane/methanol/ammonia 95/5/0.5) to afford the title compound (464 mg).
