Procedure

To a solution of the acid (27) (75 mg, 0.36 mmol) and HOBt (54 mg, 0.40 mmol) in DMF (6 mL), was added amine 9 (135 mg, 0.40 mmol). After stirring for 5 min, EDC (84 mg, 0.42 mmol) was added and the reaction mixture was stirred for additional 4 hrs at room temperature. The reaction mixture was poured into NaHCO3 solution, extracted with EtOAc; the organic phase was collected, dried over anhydrous Na2SO4 and concentrated. The residue was purified by preparative HPLC (Aquasil C-18 column, gradient MeOH/water from 60:40 to 95:5) to afford 28a (105 mg, 55% yield) as a white solid. 1H NMR (DMSO-d6) δ (ppm): 10.80 (s, 1H), 9.62 (s, 1H), 8.66 (d. 1H), 8.33 (s, 1H), 8.04 (d, 1H), 7.90 (d, 1H), 7.82 (s, 1H), 7.68 (s, 1H), 7.54-7.49 (m, 2H), 7.06 (m, 2H), 6.89 (m, 2H), 4.03 (s, 3H), 3.84 (s, 3H), 3.66 (s, 2H). MS (m/z): 532.0 (M+H).
