Procedure

To a solution of compound 5e (115.9 mg, 0.34 mmol), compound 55h (82 mg, 0.31 mmol) and EDC (87.9 mg, 0.46 mmol) in CH2Cl2 (5 mL) was added Et3N (0.13 mL, 0.92 mmol). The reaction mixture was stirred at room temperature overnight. The mixture was diluted with CH2Cl2 and H2O and the water layer was acidified to pH ˜6 with 1 N aqueous HCl. The organic solution was dried over Na2SO4 and concentrated. The residue was purified by flash column chromatography (silica gel, 2% MeOH/EtOAc) to give compound Cpd 724 (64.4 mg). 1H NMR (400 MHz, CDCl3): δ 7.89 (d, J=3.2 Hz, 1H), 7.31-7.63 (m, 9H), 4.38-4.63 (m, 2H), 4.03-4.37 (m, 6H), 3.74-3.96 (m, 2H), 3.20-3.29 (m, 1H), 3.16 (t, J=8.3 Hz, 2H), 2.38-2.61 (m, 4H). MS m/z (M+H+) 502.0.
