Procedure
Using Method A, 4-amino-8-bromo-N-cyclopropyl-cinnoline-3-carboxamide (143 mg, 0.47 mmol) and 2,6-dimethoxypyridine-3-boronic acid (170 mg, 0.94 mmol) were reacted. After purification the title compound (132 mg, 77% yield) was obtained as a white solid. 1H NMR (500 MHz, DMSO-d6) δ 9.03 (d, J=4.9 Hz, 1H), 8.38 (d, J=8.0 Hz, 1H), 7.76 (m, 2H), 7.67 (d, J=8.0 Hz, 1H), 6.48 (d, J=8.0 Hz, 1H), 3.93 (s, 3H), 3.77 (s, 3H), 2.96 (m, 1H), 0.70(m, 4H). MS APCI, m/z=366.
