Versuchsvorschrift

A mixture of 2-acetamido-6-aminopyridine (2.9 g, 19 mmol), (Angew. chem. 1995, 107, 2589), and 2,2-dimethyl-5-methoxymethylene-1,3-dioxane-4,6-dione (4.28 g, 23 mmol), (Montatsh. Chem. 1967, 98, 564), in ethanol (75 ml) was stirred and heated at reflux for 5 hours. The mixture was allowed to cool and the precipitated product was collected by filtration and dried to give 5-((6-acetamido-2-pyridylamino)methylene)-2,2-dimethyl-1,3-dioxane-4,6-dione (1.3 g, 22%) as a yellow solid.
