Versuchsvorschrift

2.00 g (14.8 mmol) dithiobiuret were placed in 25 ml methanol and 2.10 g (14.8 mmol) methyliodide were added at room temperature. The mixture was heated for 3 hours at reflux, then the solution was concentrated, was diluted with 25 ml of ethanol and 2.47 g (14.8 mmol) 2,6-dimethoxybenzylamine were added. The mixture was subsequently stirred again for 2 hours at reflux and subsequently for 30 minutes at 5° C. Filtration of the precipitate formed yielded 970 mg N-[[(2,6-dimethoxybenzyl)amino](imino)methyl]thiourea.
