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 6-methylpyridin-3-ylboronic acid were reacted. The crude material was diluted with DMF and the solids were collected by filtration to provide 135 (58 mg, 23%). 1H NMR (400 MHz, DMSO) δ 8.73 (dd, J=32.7, 2.1, 2H), 8.11 (s, 1H), 7.96 (dd, J=8.1, 2.4, 1H), 7.65 (dd, J=8.4, 2.3, 1H), 7.38 (d, J=8.1, 1H), 7.20 (d, J=8.4, 1H), 5.78 (dt, J=13.0, 6.5, 1H), 4.52-4.32 (m, 2H), 3.48 (t, J=4.9, 2H), 2.52 (s, 3H), 1.57 (d, J=6.6, 6H). MS (ESI(+)): m/z 404.1 (M+H).
