Reaction Steps
A mixture of 9-Chloro-2-[2-(2,4-difluoro-phenyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1-thia-10-aza-benzo[e]azulene (300 mg, 0.72 mmol), Pd(OAc)2 (20 mg, 0.1 mmol), isopropylamine (80 mg, 1.44 mmol), X-phos (70 mg, 0.144 mmol), tert-butoxide (140 mg, 1.44 mmol) in dioxane (2 mL) was bubbled N2 for 10 min and then stirred at 120° C. for 5 min under the irradition of microwave. The mixture was filtered over celite. The filtrate was concentrated to dryness and purified by pre-HPLC to afford 80 mg of 276 (yield=25%). 1H NMR (CDCl3, 400 MHz) δ: 8.01 (s, 1H), 7.50-7.44 (m, 1H), 7.18-7.15 (m, 1H), 7.09-6.99 (m, 3H), 6.13 (d, J=8.8 Hz, 1H), 4.19-4.14 (m, 2H), 3.96-3.80 (m, 2H), 3.45-3.41 (m, 1H), 3.06-3.04 (m, 2H), 3.18-3.12 (m, 6H). LC-MS (ESI): m/z=439 [M+H]+
