To a solution of the amine 416 (0.16 mmol) in DMF (1 mL) was added acid 27 (38 mg, 0.18 mmol), HOBT (24 mg, 0.18 mmol) and EDC×HCl (46 mg, 0.24 mmol). The mixture was stirred at room temperature for 16 h. The solvent was evaporated, then the residue was purified by flash chromatography with gradient of methanol (0-5%) in dichloromethane, followed by preparative HPLC purification with gradient of methanol (20-100%) in water to give title compound 412 (14 mg, 13% yield). MS (m/z): 659.1 (M+H). 1H NMR (DMSO-d6) δ (ppm): 10.59 (s, 1H), 9.64 (s, 1H), 9.16 (d, J=3.3 Hz, 1H), 8.69 (d, J=3.3 Hz, 1H), 8.51 (d, J=5.5 Hz, 1H), 8.07 (d, J=7.4 Hz, 1H), 7.98 (s, 1H), 7.88 (dd, J=13, 2.3 Hz, 1H), 7.51 (t, J=9.0 Hz, 1H), 7.43 (dd, J=8.8, 1.6 Hz, 1H), 7.11-7.05 (m, 2H), 6.94-6.90 (m, 1H), 6.67 (d, J=4.7 Hz, 1H), 4.05 (t, J=6.5 Hz, 2H), 3.86 (s, 3H), 3.64 (s, 2H), 3.55-3.50 (m, 4H), 2.63 (t, J=5.5 Hz, 2H), 2.46-2.42 (m, 4H).
