A tracelesssolid-phase route to 1,4-disubstituted-6-nitro-3,4-dihydro-1H-quinazolin-2-ones is described. N-Alloc-3-amino-3-(2-fluoro-5-nitrophenyl)propionic acid was tethered to Rink resin via its carboxylic group. The protected amine was coupled with an organic acid after Alloc-deprotection and the arylfluorine was displaced with a primary amine to generate a resin-bound aniline with two diversity
