실험 절차

A solution of the compound (300 mg, 0.59 mmol) obtained in Example 16-4), isoxazol-4-boronic acid (73 mg, 0.65 mmol), tetrakis(triphenylphosphine)palladium(0) (68 mg, 0.06 mmol), and potassium carbonate (163 mg, 1.18 mmol) in 1,2-dimethoxyethane (3 mL) and water (1.5 mL) was stirred at 120° C. for 1 h under microwave irradiation. The reaction mixture was cooled to room temperature, water (3 mL) was added to the reaction mixture, the mixture was extracted with ethyl acetate, and the organic layer was washed with saturated sodium chloride solution and dried with anhydrous sodium sulfate. After concentration under reduced pressure, the residue was purified by silica gel chromatography (ethyl acetate:methanol=70:30) to obtain the title compound (127 mg, 44%) as an orange solid.
