Procedure

11.1 g (0.05 mols) of N-benzoyloxalic acid dihydrazide are suspended in 250 ml of dimethylacetamide and dropwise admixed, while stirring, with 5.8 g (0.055 mols) of butyric acid chloride. The reaction mixture is stirred for 3 hours at 60°-70° C., then 500 ml of ice water are added and filtering under suction is carried out at 5°-10° C. The resultant product is recrystallised from methylcellosolve. There is obtained N-benzoyl-N'-butyroyloxalic acid dihydrazide (stabiliser 44), M.P. 254° C.
