    摘要: The invention relates to a method for the synthesis of exocyclic derivatives of cycloalkyl-hydrazines and exocyclic derivatives of heterocycloalkyl-hydrazines. The invention is characterised in that the method comprises a step consisting in demixing a solution containing said synthesised derivative, by reacting a heterocyclic amine with monochloramine, in an organic phase and an aqueous phase with the addition of anhydrous sodium hydroxide. According to the invention, the starting amine which has not reacted is collected and reused directly without any additional treatment. The inventive method can also be used to obtain the corresponding exocyclic heterocycloalkyl-hydrazine or cycloalkyl-hydrazinederivative derivative at a low cost compared to that of other known methods.

    摘要: Novel amides of aminoalkyl-substituted azetidines, pyrrolidines, piperidines and azepanes, use of these compounds as pharmaceutical compositions, pharmaceutical compositions comprising the compounds, and a method of treatment employing these compounds and compositions. The compounds show a high and selective binding affinity to the histamine H3 receptor indicating histamine H3 receptor antagonistic, inverse agonistic or agonistic activity. As a result, the compounds are useful for the treatment of diseases and disorders related to the histamine H3 receptor.
