Procedure

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 (49 mg, 0.3 mmol), morpholine (130 mg, 1.44 mmol), 2,8,9-tributyl-2,5,8,9-tetraaza-1-phosphabicyclo[3.3.3]undecane (99 mg, 0.29 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 1 h under the irradition of microwave. The mixture was filtered over ceilite. The filtrate was concentrated to dryness and purified by pre-HPLC to afford 115 mg of 110 (yield=31%). 1H NMR (CDCl3, 400 MHz): δ8.12-8.10 (m, 1H), 7.58-7.52 (m, 1H), 7.15-7.05 (m, 4H), 6.55 (d, J=9.2 Hz, 1H), 4.25-4.23 (m, 2H), 3.75-3.63 (m, 5H), 3.12-3.10 (m, 2H), 2.93-2.91 (m, 4H), 2.62-2.57 (m, 3H). LC-MS (ESI): m/z=480 [M+H]+
