Abstract

2‐Substituted 3‐formyl‐4H‐pyrido[1,2‐a]pyrimidin‐4‐ones can be synthethized by Vilsmeier‐Haack formylation with the dimethylformamide‐phosphoryl chloride complex only from those 4H‐pyrido[1,2‐a]pyrimidin‐4‐ones which contain a substituent with electron‐releasing resonance effect in position 2. The products were characterized by uv, ir and 1H nmr spectroscopy.
