反应详情

Under a nitrogen atmosphere, butyryl chloride (0.76 mL, 7.3 mmol) was added dropwise to a mixture of 3-amino-7-chloro-4-hydroxyquinoline (1.3 g, 6.7 mmol), triethylamine (3.0 mL, 21.5 mmol) and anhydrous tetrahydrofuran (20 mL). The reaction mixture was maintained at ambient temperature overnight. The resulting precipitate was isolated by filtration, washed with water followed by tetrahydrofuran, and then vacuum dried to provide 1.05 g of N-(7-chloro-4-hydroxyquinolin-3-yl)butanamide as a tan powder.
