Reaction Steps
A mixture of 7-iodo-8-phenyl-2-(2-trimethylsilanyl-ethoxymethyl)-2H-9-oxa-1,2,3a-triaza-cyclopenta[a]naphthalene-3,6-dione (53.5 mg, 0.10 mmol), 2-methyl-propane-2-sulfinic acid {3-[4-(4,4,5,5-tetramethyl[1,3,2]dioxaborolan-2-yl)-phenyl]-oxetan-3-yl}-amide (57 mg, 0.15 mmol), [1,1′-bis(diphenylphosphino)-ferrocene]dichloropalladium(II), complex with dichloromethane (4 mg, 0.005 mmol), sodium carbonate solution (2 M in water, 0.3 mL, 0.6 mmol) and DME (2 mL) was purged using nitrogen and heated in a microwave reactor at 125° C. for 1 h. The reaction mixture was allowed to cool to RT and was partitioned between EtOAc and water. The aqueous phase was extracted with EtOAc and the combined organic extracts were washed with water and brine, dried (Na2SO4), filtered, and concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 0 to 5 (% MeOH in EtOAc) to afford the title compound (46 mg, 70%) as a yellow gum. LCMS (Method H): RT=3.95 min, [M+H]+=661.
