Formation of 5-acetamido-substituted thiazoles was found to be readily effective on heating 2-(acylamino)thioacetamides with acetic anhydride. In additon, preparation of some starting 2-(acylamino)thioacetamides is described and 5-acetamidothiazole-4-carboxamides obtained by the thiazole formation reaction were led to some thiazolo[5, 4-d]pyrimidines.
