A novel and efficient aerobic protocol for the oxidative synthesis of 2-aryl quinazolinesviabenzyl C-H bond amination by a one-pot reaction of arylmethanamines with 2-aminobenzoketones and 2-aminobenzaldehydes has been carried out using the 4-hydroxy-TEMPO radical as the catalyst, without any metals or additives.
