Reaction Steps

A solution of 399 (93 mg, 0.3 mmol), phenylene diamine (65 mg, 0.6 mmol), EDC (86 mg, 0.45 mmol), HOBT (53 mg, 0.33 mmol) and Et3N (125 μL, 91 mg, 0.9 mmol) in acetonitrile (2 mL) was stirred at room temperature overnight. The reaction mixture was concentrated and the residue was purified by flash chromatography using the gradient 5-20% MeOH in DCM as an eluent to afford the title compound (24 mg, 16% yield). 1H NMR (CDCl3) δ 8.97 (s, 1H), 8.66 (d, J=4.9 Hz, 1H), 8.21 (d, J=3.9 Hz, 1H), 7.87 (d, 2H, J=8.8 Hz), 7.52 (dd, J=5.1 Hz, J=8.0 Hz, 1H), 7.15 (d, 1H, J=7.9 Hz), 7.05 (t, J=8.1 Hz, 1H), 6.89 (d, J=7.6 Hz, 1H), 6.76 (t, J=7.3 Hz, 1H), 6.66 (d, J=9.0 Hz, 2H), 4.78 (m, 1H), 3.80 (dd, J=6.7 Hz, J=10.2 Hz, 1H), 3.61 (m, 1H), 3.49 (m, 1H), 3.41 (m, 1H), 2.4 (m, 1H), 2.2 (m, 1H). LRMS: (calc) 401.2; (found) 402.2 (M+H1).
