electrophilic and nucleophilic reagents gave annulated pyrimidine derivatives 3–11, respectively. Compound 3 ([7-(dibenzothien-2-yl)-5-phenyl-2,3-dihydro-5H-thiazolo[3,2-a]-pyrimidin-6-yl]acetic acid) was transformed to pyrimidinylacetyl azide 12, which upon heterocyclisation with active methylene compounds, acidic and basic reagents furnished functionally substitutedheteroaromatic compounds 13–21,
