To a solution of 3-phenyl-3-(3-trifluoromethyl-benzenesulfonylamino)-propionic acid (4.31 g, 11.56 mmol), trifluoro-methanesulfonic acid 5-amino-5,6,7,8-tetrahydro-naphthalen-2-yl ester (Step D, 3.10 g, 10.51 mmol), HOBt (Aldrich, 1.28 g, 9.46 mmol), and CH2Cl2 (30 mL) was added EDC (Aldrich, 3.02 g, 15.76 mmol). The reaction was stirred at RT overnight and diluted with CH2Cl2 (100 mL). The organic phase was washed with saturated NaHCO3, water and brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude was purified by silica gel chromatography (16-30% EtOAc-hexane) to afford the title compound as an off-white solid. MS (ESI): 651 (M+H)+.
