Abstract(s)

Thermal and microwave initiated cyclization of 2,4-disubstituted 6-arylethynylpyrimidine-5-carbalde hydes with tert-butylamine has been studied. A novel high-yielding preparation of 2,4-disubstituted 7- arylpyrido[4,3-d]pyrimidines has been developed. The intermediate compounds were isolated and possible mechanism of the reactions is discussed.
