실험 절차

3-bromo-1,1-diphenylpropane (2.6 g, 9 mmol) and tert-butyl 4-(2-aminoethyl)piperidine-1-carboxylate (4.7 g, 21 mmol) were mixed together in acetonitrile (100 ml) and potassium carbonate (1.3 g, 9 mmol) was added. The resulting mixture was heated to 65° C. with stirring under N2 overnight. After that time the mixture was cooled and concentrated under reduced pressure. The residue was partitioned between DCM and water. The DCM layer was washed with water, dried over MgSO4 and concentrated under reduced pressure to give the crude product as a clear oil. The crude product was purified by combiflash (0-10% MeOH/DCM) to give tert-butyl 4-(2-(3,3-diphenylpropylamino)ethyl)piperidine-1-carboxylate 48.
