TL;DR: A traceless approach for the parallel solid-phase synthesis of 2-arylamino-substituted quinazolinones is described, and the desired products were obtained in good yield and purity.
Abstract: 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 amines in the present of Mukaiyama's reagent (2-chloro-1-methylpyridinium iodide) to afford resin-bound guanidines. Following intramolecular cyclization of the resin-bound guanidines during cleavage from the resin by HF/anisole (95/5) for 1.5 h at 0 °C, the desired products were obtained in good yield and purity.

TL;DR: The dual-Claisen condensation of diesters with acetoacetate dianon generated tetraoxoalkanedioates, whose aromatization by Ca(OAc) 2 -promoted intramolecular condensation constructed two carbocyclic rings containing phenol part as discussed by the authors.
