Versuchsvorschrift

N,N-Dimethylguanidine hydrochloride (3.23g; 0.026 mol.) was added to a solution of sodium (0.61 g; 0.026 mol.) in anhydrous ethanol (50 ml.) and the mixture was heated under reflux for 30 minutes. The carbamate prepared in (a) above (5.0 g., 0.026 mol.) was then added and the mixture heated under reflux for 22 hours. The ethanol was removed, water (75 ml.) added, and the pH of the solution adjusted to 6 to 7 with acetic acid. The product was collected, washed with water, and recrystallised from ethanol to give 4-dimethylamino-6-ethoxy-1,3,5-triazin-2-one.
