Versuchsvorschrift

The mixture of 10 parts by weight of 1,3-diaza-cyclohexane-2-one, 49 parts by weight of trimethylchlorosilane, 25 parts by weight of triethylamine and 150 parts by volume of dioxane were boiled for 3 days with stirring and exclusion of moisture, then filtered, evaporated to 50 parts by volume in vacuo and stirred overnight with 11.5 parts by volume of formic acid-acetic acid anhydride. The mixture was evaporated to dryness in vacuo, and the residue was recrystallized from ethanol/ether.
