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), C-(1-Methyl-pyrrolidin-3-yl)-methylamine (164 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 120 mg of 117 (yield=34%). 1H NMR (CDCl3, 400 MHz): δ8.67-8.52 (m, 1H), 8.11-8.06 (m, 1H), 7.58-7.50 (m, 1H), 7.16-7.02 (m, 3H), 6.96-6.90 (m, 1H), 6.42-6.31 (m, 1H), 4.28-4.21 (m, 2H), 3.50-2.84 (m, 8H), 2.72-2.64 (m, 3H), 2.38-2.22 (m, 1H), 1.94-1.82 (m, 1H). LC-MS (ESI): m/z=495 [M+H]+
