Ethanol → ethyl quinoline-3-carboxylate

Participants

Reaction Conditions

Reaction Steps

In a sealable tube, concentrated sulfuric acid (32 □L) was added to a solution of potassium quinoline-3-carboxylate in ethanol (1 mL). The flask was sealed and heated at 85° C. for 24 h. The mixture was cooled to ambient temperature, basified with 1 M sodium carbonate (10 mL), and the product was extracted with dichloromethane (3×15 mL). The organic fractions were dried over sodium sulfate and concentrated. Purification of the product by flash column chromatography (10% to 20% EtOAc/hexane) afforded the title compound (292 mg, 1.45 mmol). MS m/z: 202 (M+1).
