Procedure

To a solution of compound 422 (25 mg, 0.059 mmol) in DMF (0.5 mL) was added the acid 27 (25 mg, 0.12 mmol), hydroxybenzotriazole (11 mg, 0.071 mmol), then EDC (23 mg, 0.12 mmol). The reaction mixture was stirred at room temperature for 6 hours before the addition of saturated NaHCO3 (8 mL). The mixture was then extracted with dichloromethane; the extract was dried over anhydrous Na2SO4, filtered and concentrated. The residue was then purified by flash chromatography (eluent a gradient of 0 to 20% methanol in dichloromethane) to give title compound 417 as a white solid (19 mg, 53% yield). 1H NMR: (DMSO-d6) δ(ppm): 10.58 (s, 1H), 9.62 (s, 1H), 8.45 (d, J=5.6 Hz, 1H), 8.28 (d, J=2.8 Hz, 1H), 8.05 (d, J=8.4 Hz, 1H), 7.95 (dd, J=2.8, 9.6 Hz, 1H), 7.88-7.84 (m, 2H), 7.45 (t, J=8.8 Hz, 1H), 7.43-7.40 (m, 1H), 7.07-7.03 (m, 2H), 6.92-6.88 (m, 1H), 6.60 (d, J=5.6 Hz, 1H), 6.51 (d, J=9.6 Hz 1H), 4.05 (t, J=6.0 Hz, 2H), 3.84 (s, 3H), 3.62 (s, 2H), 2.53 (t, J=6.4 Hz, 2H), 2.47 (s, 6H). MS (m/z): 308.5 ([M+2H]/2), 616.1 (M+H).
