Participants

Reaction Steps

Using Method A, 4-amino-7-fluoro-8-iodo-N-cyclopropyl-cinnoline-3-carboxamide (178 mg, 0.48 mmol) and 2,6-dimethoxypyridine-3-boronic acid (176 mg, 0.96 mmol) were reacted. After purification the title compound (124 mg, 67% yield) was obtained as a white solid. 1H NMR (500 MHz, DMSO-d6) δ 9.02 (d, J=4.8 Hz, 1H), 8.51 (m, 1H), 7.73 (t, J=9.1 Hz, 1H), 7.66 (d, J=8.0 Hz, 1H), 6.51 (d, J=8.0 Hz, 1H), 3.94 (s, 3H), 3.78 (s, 3H), 2.93 (m, 1H), 0.70(m, 4H). MS APCI, m/z=384.
