A 0.25 mol solution of methylhydrazine 40% diluted in 50.0 g xylene and 4.7 g water was prepared. A solution of 0.25 mol of 2-[1-Ethoxy-meth-(Z)-ylidene]-4,4-difluoro-3-oxo-butyric acid ethyl ester in 100.0 g xylene was added to the methylhydrazine over 30-60 minutes at a temperature of 20-25° C. The reaction mixture was stirred for 15 min. The phases of the reaction mass were separated.
