Reaction of pyrimidinylacetic acid 2 with different electrophilic and nucleophilic reagents gave annulated pyrimidine derivatives 3-11, respectively. Compound 3 was transformed to pyrimidinylacetyl azide 12, which upon heterocyclization with active methylene compounds, acidic and basic reagents furnished functionally substitutedheteroaromatic compounds 13-21, respectively. The antimicrobial activity of some
