Procedure

Diethyl 2-chloro-2-[2-(8-methoxy-1-methyl-2-oxo-1,2-dihydroquinolin-5-yl)ethyl]malonate (2.38 g) was added to a mixture of acetic acid (10 ml) and 6N hydrochloric acid (15 ml), and the resulting mixture was heated under reflux overnight. After cooling to room temperature, water and a small quantity of ethanol was added to the reaction mixture, followed by ice cooling. The precipitated solid was collected by filtration, washed with water and dried to thereby obtain 0.99 g (yield: 55%) of 2-chloro-4-(8-methoxy-1-methyl-2-oxo-1,2-dihydroquinolin-5-yl)butyric acid as a gray powder.
