Reaktionsschritte

To a suspension of 3-[4-(2-methoxyphenyl)piperazino]propanohydrazide D2 (0.30 g, 1.07 mmol) in anhydrous toluene (5 mL), cyclooctyl isocyanate (0.177 g, 1.15 mmol) was added and the mixture was heated at reflux until all solid dissolved. The solution was allowed to cool slowly to room temperature. Hexane was added and the resulting oil was extracted with ethyl acetate, the organic phase was washed with water, dried over MgSO4 and evaporated under reduced pressure to afford 0.40 g (84%) N-cyclooctyl-2-{3-[4-(2-methoxyphenyl)piperazino]propanoyl}-1-hydrazine-carboxamide D3 as a colourless oil.
