Participants

Reaction Steps

Using Method A, 4-amino-7-fluoro-8-iodo-N-cyclopropyl-cinnoline-3-carboxamide (178 mg, 0.48 mmol) and 2,4-dimethoxypyrimidin-5-boronic acid (176 mg, 0.96 mmol) were reacted. After purification the title compound (73 mg, 39% yield) was obtained as a white solid. 1H NMR (500 MHz, DMSO-d6 ) δ 9.04 (d, J=4.9 Hz, 1H), 8.57 (dd, J=5.6, 9.3 Hz, 1H), 8.37 (s, 1H) 7.77 (t, J=9.1 Hz, 1H), 3.99 (s, 3H), 3.84 (s, 3H), 2.93 (m, 1H), 0.70(m, 4H). MS APCI, m/z=385.
