Reaktionsschritte

Preparation took place analogously to Example 3 by reaction of 140 mg (0.52 mmol) N-[[(2,6-dimethoxybenzyl)amino](imino)methyl]thiourea with 140 mg (0.52 mmol) 4-(trifluoromethyl)phenacyl bromide. The educts were suspended in 3 ml dioxane, were added to 0.3 ml acetic acid and were heated for 40 minutes in the microwave (radiation 300 Watt). The mixture was subsequently concentrated and the crude product obtained was purified by chromatography on silica gel (dichloromethane/methanol 1-4%). Stirring of the yellow foam obtained with methyl tert.-butyl ether yielded 120 mg of a white amorphous solid.
