Isolation of intermediates in the synthesis of thieno[2,3-d]pyrimidine-2, 4(1H,3H)-diones using microwave irradiation

Davoodnia,Zare-Bidaki,Eshghi

experimental part, p. 2968 - 2973 (2009/09/06)

A simple and fast method for the isolation of intermediates in the synthesis of 3-arylthieno[2,3-d]pyrimidine-2,4(1H,3H)-diones has been developed by microwave-assisted condensation of ethyl 2-amino-4,5-dimethylthiophene-3- carboxylate with aryl isocyanat
