A traceless approach for the parallel solid-phase synthesis of 2-arylamino-substituted quinazolinones is described. Acylation of MBHA resin with o-nitrobenzoic acid derivatives, followed by reduction of the nitro group with tin chloride, generated a resin-bound o-anilino derivative. Reaction of resin-bound o-anilino derivative with arylisothiocyanates yielded resin-bound thioureas, which reacted with
