Abstract
Reduction of a number of pyridylthiazolylketoximes gives amines, converted by p-ethoxyphenylisothiocyanate to the corresponding thioureas. It is shown that heating 3-pyridyl-,4-pyridyl-, and p-MeOC6H4-2′-thiazolylmethylthiourea in dimethylformamide gives 7-substituted 5-mercaptoimidazo-[5,1-b]thiazoles, while heating substituted 2,4′-dipyridylmethyl-and 2-pyridyl-2′-tniazolylmethylthiourea gives 1-substituted 3-mercaptoimidazo[1,5-a]pyridines,
