Pyrrolo[3,4‐ d ]‐1,2,4‐triazolo[1,5‐ a ]pyrimidinone ( 3d ), pyrido[3,4‐ d ]‐1,2,4‐triazolo[1,5‐ a ]pyrimidinone ( 3e ) and pyrido[4,3‐ e ]‐1,2,4‐triazolo[1,5‐ a ]pyrimidinone ( 4e ) derivatives representing three new ring systems were synthesised. Their structure was proved by comparing their uv and cmr spectra with those of the known benzo‐ and thieno‐1,2,4‐triazolo[1,5‐ a ]pyrimidinones used as model compounds.
