A new practical synthesis of 3-amino-substituted 5-aminopyrazoles and their tautomerism
It was found that 3-amino-substituted 5-aminopyrazoles could be effectively prepared via hydrolytic decarboxylation of the corresponding 3,5-diaminopyrazole-4-carboxylates 5 under microwave irradiation. The reactions required short time (4 min) and were successfully reproduced in a larger scale and...
