Participants

Reaction Steps

Using method A, 4-amino-8-bromo-N-propyl-cinnoline-3-carboxamide (150 mg, 0.485 mmol) and 4-fluoro-2-methoxy-phenylboronic acid (170 mg, 1.000 mmol) were reacted to afford the title compound (143 mg, 83% yield) as a white solid. 1H NMR (300 MHz, CDCl3) δ 8.55 (br, 1H), 7.87 (m, 1H), 7.74-7.67 (m, 2H), 7.34-7.27 (m, 1H), 6.83-6.72 (m, 2H), 3.69 (s, 3H), 3.45 (apparent quartet, J=7.0 Hz, 2H), 1.65 (apparent sextet, J=7.0 Hz, 2H), 0.99 (t, 3H, J=7.0 Hz). MS APCI, m/z=355 (M+H). HPLC 1.66 min.
