construction of the amino-imidazole moiety of these derivatives is achieved by using in situ generation of chloro-imidazole and reaction with their respective anilines. Thus, these N-substituted 2-imidazolines can be prepared safely and efficiently. Moreover, these compounds show potent prostacyclin antagonistic activity by inhibition of prostacyclin agonist induced ERK 1/2 phosphorylation in human erythroleukemia
