実験手順

6.10 g (28.8 mmol) 4-chloro-benzoic acid N′-(1-imino-ethyl)-hydrazide are heated to 180° C. for 30 minutes. After cooling 2.3 g product are obtained from the residue by recrystallisation in chloroform. Evaporation of the mother liquor and subsequent purification of the residue by chromatography (silica gel, petroleum ether/ethyl acetate=1:6) yield an additional 1.22 g of product. White solid.
