Highly selective and efficient synthesis of 3-arylamino-substituted 5-aminopyrazole-4-carboxylates under microwave irradiation
© 2017 Elsevier Ltd.An improved microwave-assisted method was developed for the preparation of ethyl 5-aminopyrazole carboxylates from ethyl 2-cyano-3-methylthioacrylates and hydrazine. It was shown that using microwave irradiation significantly reduced the reaction time and improved the process sel...
