Versuchsvorschrift
2-Diethoxymethyl-5-(dimethylaminomethyleneamino)pyrimidine (6.3 g, 25 mmol) and a 5% aqueous solution of potassium carbonate (69 ml) in dioxane (40 ml) were heated at reflux for 6 hours. The reaction mixture was concentrated to a yellow solid which was triturated with ether to 2-diethoxymethyl-5-aminopyrimidine as a cream solid (4.64 g, 92% yield):
