Reaction Steps

To a solution of 1-(phenyl(3-(trifluoromethyl)phenyl)methyl)piperazine (10.0 g, 31 mmol) in acetonitrile (60 mL) was added tert-butyl bromoacetate (6.1 mL, 31 mmol) dropwise from a syringe. The reaction mixture was stirred at rt for 5 min. and triethylamine (11 mL, 78 mmol) was added. Water was added after 18 h followed by CH2Cl2. The layers were separated, the aqueous layer was extracted with CH2Cl2 and the combined organic layers were washed with brine, dried over Na2SO4, and concentrated. The crude product was purified by ISCO using 0-80% EtOAc in hexanes to give the title compound (9.1 g, 67% yield) as brown oil that solidified on standing. MS (ESI, pos. ion) m/z: 435.2 (M+1).
