Procedure

Using method A, 4-amino-8-bromo-N-propyl-cinnoline-3-carboxamide (100 mg, 0.33 mmol) and 2,4-dimethoxyphenyl boronic acid (148 mg, 0.97 mmol) were reacted to afford the title compound (88 mg, 75.1% yield) as an off-white solid. 1H NMR (300 MHz, CDCl3) δ 8.57 (br, 1H), 7.84 (dd, J=8.2 Hz, J′=1.4 Hz, 1H), 7.75 (dd, J=7.1 Hz, J′=1.4 Hz, 1H), 7.68 (t, J=7.6 Hz, 1H), 7.29 (m, overlapped with CHCl3), 6.58-6.60 (m, 2H), 3.87 (s, 3H), 3.69 (s, 3H), 3.45 (q, 6.7 Hz, 2H), 1.65 (m, J=7.3 Hz, 2H), 0.99 (t, J=7.4 Hz, 3H) MS APCI, m/z=367 (M+H) HPLC 1.94 min.
