Versuchsvorschrift
10 g (59.5 mmol) of 2,6-dimethyl-4-oxo-4H-pyran-3-carboxylic acid (prepared according to the method described in Collie, J. Chem. Soc.; 1907; 787) is stirred in 100 ml of 28% aqueous ammonia at room temperature overnight. The residue is diluted with little aqueous HCl, and the solid is filtered off. There is obtained 6.9 g (69% yield) of a solid.
Aufarbeitung
- filtrationthe solid is filtered off
