Reaction Steps

A mixture of N-(2-bromoethyl)[4-(trifluoromethyl)phenyl]carboxamide (0.6 g, 2 mmol), BOC-piperazine (0.38 g, 2 mmol), and potassium carbonate (0.56 g, 4 mmol) in acetone was heated to reflux for 2 hours. The reaction was then cooled and concentrated. The product was isolated using column chromatography (EtOAc:Hexanes 1:1) to yield tert-butyl 4-(2-{[4-(trifluoromethyl)phenyl]carbonylamino}ethyl)piperazinecarboxylate (M+1=402.1)
