실험 절차

A mixture of 3-bromo-4-phenylpyridine (50 mg, 0.213 mmol), 2-butyl-5-hydroxy-isoindolin-1-one (88 mg, 0.427 mmol), Cs2CO3 (139 mg, 0.427 mmol), CuI (16.3 mg, 0.085 mmol) and 2,2,6,6-tetramethyl-3.5-heptanedione (53 μL, 0.256 mmol) in degassed N-methylpyrrolidone (NMP) (2 mL) was stirred and heated in the microwave (220° C., 300 W, 30 min). Two of those reactions were combined, excess water and ethyl acetate were added. The organic layer was separated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were extracted with aqueous HCl (2 M) and the combined extracts were basified with aqueous NaOH (2 M) followed by extraction with ethyl acetate. The combined organic layers were washed with water and dried over MgSO4. Purification by HPLC provided 2-butyl-5-(4-phenylpyridin-3-yloxy)isoindolin-1-one (16 mg, 8%).
