Reaction Steps

A suspension of 5-fluoro-2-methyl benzoic acid (2.31 g, 15.0 mmol) in dichloromethane (30 mL) containing a few drops of dimethylformamide was treated dropwise under nitrogen with oxalyl chloride (1.6 mL, 18.3 mmol). After gas evolution subsided, the reaction mixture was refluxed for an additional 10 minutes, and then evaporated to dryness. The crude acid chloride was used as such in the next step.
