STUDIES ON PYRIMIDINE DERIVATIVES. XIX. SYNTHESIS OF ISOXAZOLOPYRIMIDINES

5-Amino-3-phenylisoxazole-4-carbaldehyde (III) was synthesized by the Vilsmeier reaction of 5-amino-3-phenylisoxazole (I) via N,N-dimethyl-N'-(4-formyl-3-phenylisoxazol-5-yl)formamidine (II).Reaction of III with formamidine and ethyl imidates afforded 3-p
