Reaction Steps

To a solution of the acid 39 (58 mg, 0.32 mmol) and HOBt (47 mg, 0.35 mmol) in DMF (5 mL), was added amine 9 (108 mg, 0.32 mmol). After stirring for 5 min, EDC (75 mg, 0.39 mmol) was added and the reaction mixture was stirred overnight at room temperature then poured into dilute NaHCO3 solution and extracted with EtOAc. The extract was dried over anhydrous Na2SO4, filtered and concentrated. The residue was purified by preparative HPLC (Aquasil C-18, gradient: MeOH in water 60% to 95%) to afford the title compound 40 as a white solid. (20 mg, 12%) 1H NMR (DMSO-d6) δ (ppm): 10.65 (s, 1H), 10.50 (s, 1H), 8.73 (d, 1H), 8.50 (d, 1H), 8.26 (dd, 1H), 8.05 (m, 1H), 7.88 (s, 1H), 7.87 (dd, 1H), 7.48 (t, 1H), 7.41 (m, 2H), 7.35 (m, 1H), 6.69 (d, 1H), 3.99 (s, 3H), 3.56 (s, 2H). MS (m/z): 503.1 (M+H).
