To a solution of 95 (136 mg, 0.37 mmol) in dry DMF (7 ml) was added the acid 27 (300 mg, 3.0 eq, 1.1 mmol), HOBT (74 mg, 1.5 eq, 0.55 mmol) and EDC (210 mg, 3.0 eq, 1.1 mmol) and the reaction mixture was stirred at RT overnight. The reaction mixture was concentrated to dryness and partitioned between EtOAc and sat NaHCO3 soln, the organic phase was collected, dried over anhydrous sodium sulfate and filtered. The solvent was removed under reduced pressure and the crude was triturated with Et2O to afford title compound 92 (150 mg, 72% yield). 1H NMR (DMSO-d6) δ (ppm): 10.57 (s, 1H), 9.62 (s, 1H), 8.43 (d, J=5.48 Hz, 1H), 8.06 (m, 2H), 7.93 (m, 1H), 7.85 (m, 1H), 7.76 (s, 1H), 7.45 (m, 2H), 7.05 (m, 2H), 6.90 (m, 1H), 6.58 (m, 1H), 5.35 (s, 2H), 3.84 (m, 3H), 3.63 (s, 2H), 3.25 (s, 3H). MS (m/z): 562.1 (M+H).
