title: Synthesis of new fused pyrimidines by isocyanate and isothiocyanate.
abstract: o-Aminonitrile or o-aminoester compounds were cyclized to fused pyrimidines by reacting with ethyl iso(thio)cyanatoacetate in pyridine, and then were methylated, halogenated and subsequently displaced by the amines studied.
