The present invention provides a multistep process for the preparation of .beta.-cyclo-substituted ethylamines of the general formula:- Ar--CH.sub.2 --CH.sub.2 --NH.sub.2 (I) in which AR is a heterocyclic or non-heterocyclic aromatic radical, which is optionally mono- or poly- substituted, wherein said compounds represent a class of intermediates which can be converted to 4,5,6,7-tetrahydro[3,2-C] or [2,3-C]pyridines wherein the latter are useful for anti-inflammatory, vasodilator or blood platelet aggregation inhibition activities.
本发明提供了一种用于制备β-环代替乙胺的多步骤过程,其一般公式为:Ar--CH.sub.2 --CH.sub.2 --NH.sub.2(I),其中Ar是一种杂环或非杂环芳基,可以是单取代或多取代的,所述化合物代表一类中间体,可以转化为4,5,6,7-四氢[3,2-C]或[2,3-C]吡啶,后者可用于抗炎、扩血管或抑制血小板聚集活性。
