thermal rearrangement in water. On the basis of the above findings, an eco-friendly method was applied to prepare quinazolin-4(1H)-one derivatives from anthranilamides and a number of (hetero)aryl aldehydes. Heating the aqueous mixture of starting compounds to 90 °C resulted in the products in 81–94% yields. All products precipitated from the reaction mixture and were isolated by simply filtration.
