실험 절차

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 5-cyclopropylisoxazol-3-amine (80 mg, 0.65 mmol), XantPhos (29 mg, 0.050 mmol), Pd2 dba3 (45 mg, 0.050 mmol), [4-(5-bromo-1-methyl-6-oxo-1,6-dihydropyridin-3-yl)-2-{4,4-dimethyl-9-oxo-1,10-diazatricy-clo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-3-yl]methyl acetate 273a (350 mg, 0.65 mmol), Cs2CO3 (390 mg, 1.2 mmol), and 1,4-dioxane (10 mL). After bubbling nitrogen through the resulting mixture for 10 minutes, it was heated at reflux for 2 h. The mixture was then evaporated under reduced pressure and the residue was partitioned between ethyl acetate (20 mL) and water (10 mL). The organic layer was concentrated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with 20:1 dichloromethane/methanol to afford 311a (120 mg, 32%) as a brown solid. MS-ESI: [M+H]+ 583.2.
