Oxalyl chloride → 2-Fluoro-4-formylbenzoyl chloride

Participants

Reaction Steps

To a slurry of 2-fluoro-4-formylbenzoic acid (0.531 g, 3.16 mmol) 10 mL DCM was added oxalyl chloride (0.168 mL, 1.89 mmol) and catalytic DMF (2 drops). The reaction was allowed to stir under a positive pressure of argon with a needle outlet to air. After 2 h, a quenched aliquot of the reaction (MeOH) was determined to contain no acid. The reaction was concentrated in vacuo and dried on a hood pump for 10 min to give a yellow solid, which was used without further purification.
