Versuchsvorschrift
A mixture of 65 g (309.1 mmol) N-1,3-thiazole-2-yl-1H-imidazole-1-carbothioamide and 260 g of ammonium acetate were heated to 80° C. in 400 ml ethanol for 1.5 hours; after completion of reaction the solvent was distilled off and water was added to the obtained residue. After extraction with CH2Cl2 and drying of the organic phase with Na2SO4, 59.6 g of the target product were obtained.
