Procedure

To a solution of compound 5e (89.5 mg, 0.261 mmol), compound 55f (60 mg, 0.237 mmol), and EDC (68.1 mg, 0.356 mmol) in CH2Cl2 (5 mL) was added Et3N (0.1 mL, 0.711 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 1N aqueous HCl. The organic solution was dried over Na2SO4 and concentrated. The residue was purified by reverse phase chromatography to give Cpd 994 as a TFA salt (40.4 mg). 1H NMR (400 MHz, CD3OD): δ 7.98 (d, J=3.2 Hz, 1H), 7.89 (d, J=3.2 Hz, 1H), 7.36-7.44 (m, 2H), 7.29-7.36 (m, 4H), 7.22-7.29 (m, 1H), 6.52 (d, J=8.3 Hz, 1H), 4.39-4.91 (m, 6H), 4.38 (s, 2H), 3.99-4.23 (m, 3H), 3.48 (t, J=8.6 Hz, 2H), 3.42 (br. s., 4H), 3.01 (t, J=8.6 Hz, 2H). MS m/z (M+H+) 488.1.
