(2-Methoxypyridin-3-yl)boronic acid → 4-amino-N-cyclopropyl-8-(2-methoxypyridin-3-yl)cinnoline-3-carboxamide

Participants

Reaction Steps

Using Method A, 4-amino-8-bromo-N-cyclopropyl-cinnoline-3-carboxamide (143 mg, 0.47 mmol) and 2-methoxypyridine-3-boronic acid (142 mg, 0.94 mmol) were reacted. After purification the title compound (118 mg, 76% yield) was obtained as a white solid. 1H NMR (500 MHz, DMSO-d6) δ 9.04(d, J=4.9 Hz, 1H), 8.43 (m, 1H), 8.24 (d, J=5.0 Hz, 1H), 7.77 (m, 2H), 7.71 (a d, J=7.2 Hz, 1H), 7.71 (a dd, J=5.1, 7.2 Hz, 1H), 3.73 (s, 3H), 2.95 (m, 1H), 0.67 (m, 4H). MS APCI, m/z=336.
