Versuchsvorschrift

To a solution of diethyl (2-chloro-6-methylquinolin-4-yl)propanedioate (100 mg, 0.30 mmol) in methanol (2 mL) was added an aqueous solution of sodium hydroxide (2 N, 2 mL) and the resulting mixture was stirred at room temperature overnight. The reaction was then acidified to pH 4 with an aqueous solution of hydrochloric acid (5 N), and extracted with ethyl acetate (10 mL×3). The organic layer was dried over sodium sulfate and concentrated in vacuo to afford the desired product as a white solid. MS (ESI+) [(M+H)+] 236.
