Procedure
Using method C, 4-amino-8-iodo-N-propyl-cinnoline-3-carboxamide (178 mg, 0.500 mmol) and 2-(tributylstannyl)pyrazine (219 mg, 0.600 mmol) were reacted to afford the title compound (70 mg, 45% yield) as an off-white solid. 1H NMR (300 MHz, CDCl3) δ 9.41 (m, 1H), 8.74 (m, 1H), 8.61 (d, J=2.5 Hz, 1H), 8.54 (br, 1H), 8.22 (m, 1H), 7.99 (m, 1H), 7.85-7.78 (m, 1H), 3.48 (apparent quartet, J=7.0 Hz, 2H), 1.69 (apparent sextet, J=7.0 Hz, 2H), 1.20 (t, J=7.0 Hz, 3H). MS APCI, m/z=309 (M+H) HPLC 1.49 min.
