Reaction Steps

tert-Butyl (Z)-4-[4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)-2-(prop-1-en-1-yl)phenyl]piperazine-1-carboxylate (85 mg, 0.181 mmol) was dissolved in N,N′-dimethylformamide (1.8 mL), added sodium hydride (9.5 mg, 217 mmol) and benzyl bromide (23 μL, 0.190 mmol) under ice-cold conditions, and the mixture was stirred at room temperature overnight. The reaction solution was added water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. The obtained residue was purified by silica-gel column chromatography (hexane/acetone). The title compound (67 mg) was obtained as a yellow oil.
