Abstract

Improved process for the preparation of oxadiazole-1,3,4-one-2 derivatives of the general formula: ** (See formula) ** wherein R represents a substituent, characterized in that a sodium or potassium hypobromite is reacted at low temperature, in the presence of soda or potash, with an acylurea of the general formula: R - CO - NH - CO - NH2 (II) then an acid is added to release the compound (I) of its sodium or potassium salt obtained in the preceding phase and finally the compound (I) thus obtained is separated by application of the convenient method.
