摘要

Abstract 5-Oxo-5H-[1, 3] thiazolo [3, 2-a] pyrimidine-6-carboxylic acid (4), and 6- methylimidazo [2, 1-b] thiazole-5-carboxylic acid (17) were reacted with amines 6a-i by the reaction with oxalyl chloride and N, N-di methyl-formamide as a catalyst into primary and secondary amide derivatives 7-14 and 19-22. From compound 24 N, N'-disubstituted ureas 26, 27 and perhydroimidazo [1, 5-c] thiazole 29 derivatives of imidazo [2, 1-b] thiazole ...
