Participants

Conditions

Temperature: -10 °C

Procedure

11.7 ml (136.3 mmol) of oxalyl chloride were dissolved in 150 ml of CH2Cl2. The solution was cooled at −10° C. and 20 g (80.2 mmol) of commercially available 2-phenylquinoline-4-carboxylic acid were added portionwise. The reaction mixture was left overnight at room temperature and then evaporated to dryness to yield 22 g of the title compound, used without further purification.
