Oxidation of 2-(substituted thio) quinazolines in THF and aqueous media using stoichiometric amounts of oxone afforded their corresponding 2-(substituted sulfonyl)quinazolines with excellent selectivity (75-94% yield). This versatile synthetic protocol proved efficient with various substituted thio quinazoline compounds as substrates. All the twelve products were characterized by melting range, infrared, 1H-NMR, 13C-NMR and mass spectrometry.
