摘要

5(4-Pyridyl)-6(4-fluorophenyl)-2,3-dihydroimidazo -[2,1-b] thiazole has significant antiarthritic and immunoregulatory activity compared with its 5,6-transposed isomer. The compound is prepared by reacting 4-(4-pyridyl-5-[4-fluorophenyl) -2-mercaptoimidazole with a reactive ethylene dihalide then separating the isomeric mixture of products.
