Reaction Steps

Using Method A, 4-amino-7-fluoro-8-iodo-N-cyclopropyl-cinnoline-3-carboxamide (175 mg, 0.48 mmol) and 5-fluoro-6-methoxypyridine-3-boronic acid (162 mg, 0.96 mmol) were reacted. After purification the title compound (106 mg, 61% yield) was obtained as a white solid. 1H NMR (300 MHz, CDCl3) δ 8.48 (bm, 1H), 8.15 (m, 1H), 7.92 (a dd, J=5.2, 9.0 Hz, 1H), 7.65 (a d, J=10.7 Hz, 1H), 7.56 (a t, J=9.0 Hz, 1H), 4.10(s, 3H), 2.96 (m, 1H), 0.88 (m, 2H), 0.65 (m, 2H). MS APCI, m/z=372, HPLC 2.59 min.
