Procedure

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a suspension of 2-(5-oxo-hexyl)-oxazole-4-carboxylic acid (403 mg, 1.91 mmol) in toluene (19 mL) was treated at 0° C. with a drop of DMF followed by oxalyl chloride (0.20 mL, 2.29 mmol) and the resulting yellow solution was stirred at rt for 1 h. The solvent was then removed under reduced pressure (coevaporation with toluene) to give 2-(5-oxo-hexyl)-oxazole-4-carbonyl chloride as a brown oil.
