Abstract A facile and efficient approach was developed to access 5, 7-disubstitued thiazolo[5,4- d ]pyrimidine-4, 6(5 H , 7 H )-diones through condensation of N -substituted 5-amino-4-carbethoxythiazole with structurally diverse isocyanates in the presence of sodium hydride. The easy availability of substrates and tolerance of structural diversity in this reaction make it attractive to be used for
