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), 1-(trimethylsilyloxy)propan-2-amine (211 mg, 1.44 mmol), tBuONa (47 mg, 0.48 mmol), Pd(OAc)2 (16 mg, 0.1 mmol), and Xphos (68 mg, 0.144 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) and pre-HPLC to afford 40 mg of 347. (yield: 13%). 1H NMR (CDCl3, 400 MHz): δ8.02 (s, 1H), 7.49 (q, J=5.6, 8.8 Hz, 1H), 7.12-6.99 (m, 4H), 6.21 (d, J=4.8 Hz, 1H), 4.20-3.04 (m, 8H), 2.28 (s, 1H), 1.19-1.15 (m, 3H). LC-MS (ESI): m/z=456 [M+H]+
