Versuchsvorschrift

Potassium carbonate (19.87 g, 143.8 mmol) and triethylamine (50.1 mL, 359 mmol) were sequentially added with stirring to a solution of 4-chloro-3-nitroquinoline (30.0 g, 144 mmol) in chloroform (200 mL). After 15 minutes, β-alanine ethyl ester hydrochloride (26.5 g, 173 mmol) was slowly added, and the reaction was stirred overnight at ambient temperature. Water (100 mL) was added, and the mixture was stirred for 15 minutes. The organic layer was separated, washed sequentially with saturated aqueous sodium bicarbonate and brine, dried over magnesium sulfate, filtered, and concentrated under reduced pressure to provide 27.4 g of ethyl N-(3-nitroquinolin-4-yl)-β-alaninate as a yellow solid, which was used without purification.
