With bis-triphenylphosphine-palladium(II) chloride; sodium carbonate; In 1,4-dioxane; water; at 150.0℃; for 0.25h;Microwave irradiation;
To a mixed solution of the compound 1 (100 mg), the compound 2 (109 mg), and dichlorobis(triphenylphosphine)palladium (12 mg) in dioxane (3.3 mL) was added an aqueous solution of 2 mol/L sodium carbonate (0.7 mL), the reactionmixture was stirred for 15 minutes at 150 C in a microwave reactor (Initiator, Biotage). The reaction mixture was cooledto room temperature, diluted with ethyl acetate, and then washed with water and brine, dried over anhydrous sodiumsulfate, and filtered. The solvent was evaporated under reduced pressure, and the resulting residue was purified bysilica gel column chromatography (eluent: hexane-ethyl acetate; gradient: 85:15-50:50) to give the compound 3 (97 mg)as a yellow solid.
