Versuchsvorschrift
To a suspension of 20.0 g (0.112 mol) of thiosalicylic acid in 200 mL of 1,2-dichlorobenzene was added 21.6 mL (0.323 mol) of ethylenediamine. The mixture was refluxed under nitrogen for 4 h then cooled to ca. 60° C. and 50 mL of methanol was added. The solution was allowed to stand at 22° C. over night and the resulting yellow crystalline solid collected and washed with ether to give 10.6 g of pure product.
