Reaction Steps

A mixture of 4-(1-N-trifluoroacetyl-4-piperazinyl)aniline (3.0 g, 9.9 mmol), Et3N (2.2 mL, 19 mmol), HOBt (1.5 g, 9.9 mmol), 1-t-butyloxycarbonyl-4-carboxypiperidine (2.3 g, 9.9 mmol) and EDC (1.9 g, 9.9 mmol) in DMF (15 mL) was stirred at RT for 18 hr. Solution was concentrated and the residue was dissolved in EtOAc. EtOAc was washed with: H2O, 5% citric acid (2×), water, 5% NaHCO3 (2×), water and brine. EtOAc was concentrated to givethe title compound (4.35 g, 91%). MS (ES) m/e 485 [M+H]+.
