Synthesis of 5-aminothiazolo[4,5-b]pyridine-2-carboxamides
摘要:
A method for the synthesis of 5-aminothiazolo[4,5-b]pyridine-2-carboxamides was proposed. The method involves oxidation of monothiooxamides derived from 2,6-diaminopyridine.
A convenient method for the synthesis of monothiooxamides by the reaction of chloroacetamides with a solution of elemental sulfur in amines was developed.
