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.
本发明提供了一种多步法制备一般式为Ar-CH2-CH2-NH2(I)的β-环替基乙胺的方法,其中AR是杂环或非杂环芳香基团,可选地为单或多取代基团,所述化合物代表一类中间体,可转化为4,5,6,7-四氢[3,2-C]或[2,3-C]吡啶,后者对抗炎、扩张血管或抑制血小板聚集活性具有用处。
