Procedure
Using Method A, 4-amino-8-bromo-N-cyclobutyl-cinnoline-3-carboxamide (145 mg) and 4-methoxypyridin-3-yl boronic acid (172 mg) were reacted to afford the title compound (31 mg) as white solid. 1H NMR (500 MHz, DMSO-d6) δ 9.24 (d, 1H), 8.52 (m, 1H), 8.44 (m, 1H), 8.33 (s, 1H), 7.78 (m, 2H), 7.18 (d, 1H), 4.49 (m, 1H), 3.72 (s, 3H), 2.26-2.10(m, 4H), 1.72-1.62 (m, 2H). MS APCI, m/z=350 (M+H).
