supported on silica gel is an efficient medium for one‐pot synthesis of (3H)‐quinazolin‐4‐ones in the absence of solvent undermicrowaveirradiation or classicalheating. The reaction of orthoesters with 2‐aminobenzamides ends up with the formation of monosubstituted (3H)‐quinazolin‐4‐ones. One‐pot synthesis of disubstituted (3H)‐quinazolin‐4‐ones is also achieved by the reaction of isatoic anhydride

Quinazolin-4(3H)-one derivatives were synthesized successfully via a one-pot, three component reaction of isatoic anhydride and an orthoester with ammoniumacetate or a primary amine catalyzed by silica sulfuric acid under solvent-free conditions. This is the first report on the synthesis of 2-substituted quinazolin-4(3H)-ones by this procedure.
