Procedure

To a solution of aniline 380 (0.31 g, 0.71 mmol) and DIPEA (0.7 ml, 0.4 g, 3 mmol) in dry DMF (5 mL) was added acid 27 (0.30 g, 1.4 mmol), HOBt (0.040 g, 0.30 mmol), and EDC×HCl (0.40 g, 2.1 mmol) and the mixture was stirred at r.t. for 18 h. Additional EDC×HCl (0.050 g, 0.26 mmol) was added, and the mixture was stirred for a further 6 h. It was then partitioned between ethyl acetate and water. The organic phase was collected, washed with water, dried (anhydrous MgSO4), filtered, and concentrated. Flash chromatography (chloroform/NH4OH) of the residue followed by re-crystallization (90% ethyl acetate/methanol) provided 378 (0.15 g, 32% yield) as a colorless solid. 1H NMR (400 MHz. DMSO-d6) δ (ppm): 10.58 (br s, 1H); 9.63 (br s, 1H); 8.68 (dd, J=2.7, 0.8, 1H); 8.48 (d, J=5.5, 1H); 8.20 (dd, J=8.6, 2.7, 1H); 8.05 (d, J=7.6, 1H); 8.03 (s, 1H); 7.86 (dd, J=13.1, 2.3, 1H); 7.49 (t, J=8.8, 1H); 7.42 (dd, J=8.8, 1.4, 1H); 7.09-7.03 (m, 2H); 6.94 (dd, J=8.8, 0.7, 1H); 6.92-6.88 (m, 1H); 6.61 (dd, J=5.5, 1.0, 1H); 4.33 (t, J=6.7, 2H); 3.85 (s, 3H); 3.63 (s, 2H); 2.33 (t, J=7.2, 2H); 2.13 (s, 6H); 1.84 (quint, J=7.2, 2H). LRMS (M+H): 630.2.
