実験手順
3.4 g. Phenethylhydrazine hydrochloride are dissolved in 10 ml. water and mixed with 1.7 g. pyruvamide dissolved in 50 ml. water. 2.1 g. sodium acetate trihydrate are added thereto and the reaction mixture well shaken up. 2-(Phenethylhydrazono)-propionamide crystallizes out. It is filtered off and recrystallized from a mixture of cyclohexane and toluene. The yield is 2.0 g. (50% of theory); m.p. 78° C. (decomp.).
