Procedure

Using method C, 4-amino-8-iodo-N-propyl-cinnoline-3-carboxamide (178 mg, 0.500 mmol) and 2-(tributylstannyl)pyridine (220 mg, 0.600 mmol) were reacted to afford the title compound (60 mg, 39% yield) as a yellow solid. 1H NMR (300 MHz, CDCl3) δ 8.79 (m, 1H), 8.52 (br, 1H), 8.26-8.21 (m, 1H), 8.14-8.09 (m, 1H), 8.05-7.98 (m, 1H), 7.88-7.75 (m, 2H), 7.34 (m, 1H), 3.47 (apparent quartet, J=7.0 Hz, 2H), 1.68 (apparent sextet, J=7.0 Hz, 2H), 1.01 (t, J=7.0 Hz, 3H). MS APCI, m/z=308 (M+H). HPLC 1.53 min.
