Procedure

To a suspension of 3-quinolinecarboxylic acid (580 mg, 3.35 mmol) in dichloromethane (25 mL) was added oxalyl chloride (2M in CH2Cl2, 3.4 mL, 6.7 mmol) dropwise at room temperature. DMF (1 drop) was added, resulting in immediate gas formation. The reaction mixture was stirred at room temperature for 2 h. Dichloromethane was evaporated. Additional dichloromethane (20 mL) was added to the residue. Concentration of the organic solvent gave the crude product. (640 mg, 99%).
