Procedure

Following the procedure for 128, 9-Bromo-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene from Example 6 and 2-methoxypyridin-3-ylboronic acid were reacted. The crude material was dissolved in DMF and purified by reverse phase HPLC to provide 129 (200 mg, 60%). 1H NMR (400 MHz, DMSO) δ 8.66 (d, J=2.2, 1H), 8.19 (dd, J=4.9, 1.7, 1H), 8.10 (s, 1H), 7.79 (dd, J=7.3, 1.8, 1H), 7.50 (dd, J=8.4, 2.3, 1H), 7.21-7.09 (m, 2H), 5.75 (dt, J=13.3, 6.7, 1H), 4.42 (t, J=4.9, 2H), 3.91 (s, 3H), 3.47 (t, J=4.9, 2H), 1.52 (d, J=6.6, 6H). MS (ESI(+)): m/z 420.1 (M+H).
