The acylation of 2-aminoquinazol-4-one by unsaturated acid chlorides proceeds principally at the exocyclic nitrogen atom and is complicated in the case of acryloyl chloride by a further intramolecular condensation forming 1,2,3,4tetrahydropyrimido(2,l-b)quinazolin-2,6-dione. A lower acylation tempe
