We describe a practical solid phase synthesis of quinazoline-2,4-diones using a short-chain, high loading capacity, polyethyleneglycol polystyrene copolymer ("PEG(4)-PS" resin). The highlights of this synthesis include efficient acyl azide formation on the solid phase, Curtius rearrangement, and cyclocleavage with K2CO3 followed by simple product isolation.
