抄録

The single step synthesis of 4(3<I>H</I>)-quinazolinones has been carried out efficiently by coupling of the three components, anthranilic acid, ortho esters, and amines in the presence of silica-supported sodium hydrogen sulfate (NaHSO<SUB>4</SUB>·SiO<SUB>2</SUB>) or Amberlyst-15 as a heterogeneous catalyst. The reaction occurred within a few minutes under solvent free conditions to afford the products in excellent yields. One of the catalysts, Amberlyst-15 can be recovered and recycled.
