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), Methyl-(2-trimethylsilanyloxy-ethyl)-amine (211 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 125° C. for 7 min under the irradition of microwave. The mixture was filtered over ceilite. The filtrate was concentrated to dryness and purified by pre-TLC (EtOAc:PE=2:1) to afford 85 mg of 242. (yield=26%). 1H NMR (CDCl3, 400 MHz): δ8.01-8.00 (m, 1H), 7.50-7.45 (m, 1H), 7.13-7.00 (m, 4H), 6.36 (d, J=9.2 Hz, 1H), 4.17-4.15 (m, 2H), 3.78-3.75 (m, 1H), 3.63-3.59 (m, 2H), 3.07-3.05 (m, 2H), 2.98 (s, 3H), 2.30-2.26 (m, 1H). LC-MS (ESI): m/z=456 [M+H]+
