Versuchsvorschrift
0.5 g (2.63 mmol) of 5-(pyridin-3-yl)-1,2-oxazole-3-carboxylic acid (known from the literature, no reference) in 25 ml of dichloromethane was admixed with 2 drops of N,N-dimethylformamide. Subsequently, 0.97 g (7.63 mmol) of oxalyl chloride was added dropwise under argon and the reaction mixture was stirred at room temperature for 1 hour. The solvent was removed under reduced pressure and the crude product was converted farther immediately.
