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 (49 mg, 0.3 mmol), phenethylamine (174 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 90 mg of 126 (yield=25%). 1H NMR (CDCl3, 400 MHz): δ8.02 (s, 1H), 7.47-7.45 (m, 1H), 7.40-7.32 (m, 2H), 7.20-7.12 (m, 2H), 7.09 (s, 1H), 7.00-7.90 (m, 3H), 6.11 (d, J=8.4 Hz, 1H), 4.18-4.16 (m, 2H), 3.53-3.47 (m, 2H), 3.07-3.03 (m, 2H), 2.87-2.82 (m, 2H). LC-MS (ESI): m/z=502 [M+H]+
