Abstract Five 2-amino-4-(x-pyridyl)-and 2-amino-4-(x-quinolyl) thiazoles have been synthesized by the condensation of thiourea with bromoacetylpyridines and-quinolines. The reaction of pyridyl pyridylmethyl ketones with thiourea and halogens produced four 2- aminothiazoles possessing pyridyl substituents in 4-and 5-positions on the thiazole ring. Treatment of N-(3-pyridyl)-and N-(3-quinoiyl) thiourea with α-bromoketones gave seven ...
