Versuchsvorschrift
Using method A, 4-amino-7-fluoro-8-iodo-N-propyl-cinnoline-3-carboxamide (250 mg, 0.67 mmol) and (2-fluoro-3-methoxyphenyl)boronic acid (193.4 mg, 1.136 mmol) were reacted to afford the title compound (72.0 mg, 29% yield) as an off-white solid. 1H NMR (500 MHz, CDCl3) δ 8.49 (bs, 1H), 7.94 (d×d, J=4.9 Hz, J=9.2 Hz, 1H), 7.55 (t, J=8.5 Hz, 1H), 7.21 (m, 1H), 7.03-7.10(m, 2H), 3.94 (s, 3H), 3.44 (q, J=6.7 Hz, J=13.4 Hz, 2H), 1.64 (apparent sextet, J=7.3 Hz, 2H), 0.98 (t, J=7.3 Hz, 3H). MS APCI, m/z=373 (M+H) HPLC 2.72 min.
