Procedure

To a mixture of compound 5e (42.9 mg, 0.132 mmol), compound 53e (30.6 mg, 0.12 mmol), and Et3N (0.084 mL, 0.6 mmol) in CH2Cl2 (1 mL) at room temperature was added HATU (70 mg, 0.168 mmol). The reaction mixture was stirred at room temperature overnight. The mixture was diluted with CH2Cl2 and H2O, washed with aq. NaHCO3 and brine, dried over Na2SO4, filtered, and concentrated. The residue was purified by flash column chromatography (silica gel, 2-4% MeOH/EtOAc) to give Cpd 1317 (45.4 mg). 1H NMR (400 MHz, CDCl3): δ 8.56 (br. s., 1H), 7.83-7.94 (m, 3H), 7.57-7.65 (m, 2H), 7.55 (d, J=3.2 Hz, 1H), 7.46 (d, J=2.4 Hz, 1H), 7.40-7.45 (m, 1H), 7.13-7.20 (m, 2H), 4.07-4.66 (m, 6H), 3.76-4.01 (m, 2H), 3.21-3.36 (m, 1H), 2.38-2.64 (m, 4H). MS m/z (M+H+) 490.2.
