A practical approach was developed for the synthesis of 4-arylquinazoline compounds
through a one-pot nucleophilic arylation/alkylation of 2-chloroquinazoline with aryl
lithium compounds generated in situ, followed by ring oxidation. The obtained 2-chloro-4-arylquinazoline
adducts were further used as versatile intermediates that undergo a variety of synthetic
transformations to provide functionalized quinazoline compounds. The arylation intermediate
dihydroquinazoline was also elaborated to the tricyclic dihydroimidazo[2,1-b]quinazolinone.
