Procedure
Using Method A, 4-amino-7-fluoro-8-iodo-N-cyclopropyl-cinnoline-3-carboxamide (188 mg, 0.50 mmol) and 2-methoxypyridine-3-boronic acid (155 mg, 1.01 mmol) were reacted. After purification the title compound (110 mg, 62% yield) was obtained as a white solid. 1H NMR (300 MHz, CDCl3) δ 8.48 (bm, 1H), 8.29 (ad, J=5.0 Hz, 1H), 7.91 (a dd, J=5.2, 9.2 Hz, 1H), 7.67 (a d, J=7.3 Hz, 1H), 7.56 (a t, J=8.9 Hz, 1H), 7.05 (a dd, J=5.0, 7.3 Hz, 1H), 3.88 (s, 3H), 2.96 (m, 1H), 0.88 (m, 2H), 0.65 (m, 2H). MS APCI, m/z=354, HPLC 2.23 min.
