Procedure

A solution of 385 (640 mg, 1.97 mmol) in MeCN (10 mL) was sequentially treated with Et3N (831 μL, 603 mg, 5.96 mmol), EDC (571 mg, 2.98 mmol), HOBT (334 mg, 2.18 mmol) and 1,2-phenylene diamine (429 mg, 3.97 mmol) and allowed to stir overnight. The reaction mixture was concentrated and partitioned between DCM (15 mL) and saturated NH4Cl (15 mL). The organic phase was collected, dried with Na2SO4, filtered and concentrated. The resultant solid was purified by flash chromatography using the gradient 3-15% MeOH in DCM to afford the title compound (113 mg, 14% yield). 1H NMR (DMSO-d6) δ9.65 (s, 1H), 8.43 (s, 1H), 7.92 (m, 3H), 7.48 (d, J=8.0 Hz, 2H), 7.16 (d, J=7.4 Hz, 1H), 6.97 (t, J=7.6 Hz, 1H), 6.81 (t, J=8.2 Hz, 2H), 6.63 (t, J=7.4 Hz, 1H), 5.85 (s, 1H), 4.34 (s, 2H), 3.85 (s, 3H). LRMS: (calc) 414.2; (found) 415.3 (M+H1)
