Reaction Steps

Mix (3-nitro-5-(trifluoromethyl)phenyl)piperazine (200 mg, 0.73 mmol), 2-fluoroethyl 4-methylbenzenesulfonate (320 mg, 1.46 mmol) and 4-dimethylaminopyridine (50 mg, 0.37 mmol) in THF (15 mL), stir at 90° C. overnight. TLC (EtOAc:PE=1:1) shows the reaction is complete. Concentrate under reduced pressure to give a residue, purify the residue by flash chromatography (silica gel, PE:EtOAc=1:1) to yield a white solid as the target compound (120 mg, 51%).
