Procedure

58.7 g (0.25 mole) of 2,6-diethyl-anilino-acetic acid ethyl ester and 25 g of hydrazine hydrate were left to stand in 200 ml of ethanol for 24 hours. Thereafter, the mixture was concentrated by distilling off the solvent and the residue was extracted by stirring with water. After drying, 50.5 g (91% of theory) of colorless crystals of 2,6-diethyl-anilino-acetic acid hydrazide of melting point 71° to 73° C. were obtained.
