Direct synthesis and cytotoxicity activity of new series of pyrido[2,3-d]pyrimidine was described. Nicotinamide 2 was synthesized via cyclization of N-cyclohexyl derivative with cyanoacetamide. The o-aminonicotinonitrile 2 was subjected to acylation or thio acylation process followed by intramolecular heterocyclization to afford the desired pyrido[2,3-d]pyrimidine (3–10) and pyrido triazine 11.
