## Abstract The previously unknown title compounds (IV) are synthesized through thermal intramolecular cyclocondensation of hydrazones (III).
## Abstract magnified image A series of 2β(3β(trifluoromethyl)β5β(alkoxy)β1__H__βpyrazolβ1βyl)β4βaryloxypyrimidine derivatives were designed and synthesized. The structures of all the title compounds were confirmed by ^1^H NMR and elementary analysis. These compounds were screened for herbicidal a
