Procedure: The 4,5-diacyl-[1,4,5]-oxadiazepines obtained in this reaction step can be obtained especially by precipitation from alcohols such as methanol, ethanol, propanol, isopropanol, methoxyisopropanol and ethoxyethanol. They are generally obtained in yields of from 40 to 76% and in a purity of more than 95%. It is not necessary, however, to isolate those intermediates; they can be introduced directly into the next step by replacing the solvent of reaction step (1) by the solvent of reaction step (2).
