Several 2- and 5-substituted oxazolo[5,4-d]pyrimidines have been prepared from 5-amino-4-cyanooxazole derivatives via N-ethoxymethylene intermediates in order to compare them with purine derivatives. Spectroscopic data and some chemical properties of these compounds were examined. A convenient method for the preparation of a starting material was described.
