実験手順

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a suspension of 5-(4-fluoro-phenyl)-oxazole-4-carboxylic acid (51 mg, 0.25 mmol) in toluene (1.0 mL) was treated with a drop of DMF followed by oxalyl chloride (0.08 mL, 0.86 mmol) and the resulting yellow solution was stirred at rt for 30 min. The solvent was then removed under reduced pressure (coevaporation with toluene) to give 5-(4-fluoro-phenyl)-oxazole-4-carbonyl chloride.
