A one-pot synthesis of 2,4-disubstituted quinazoline derivatives from halofluorobenzenes with nitriles was reported, via sequential nucleophilic addition and SNAr reaction. The advantages of the present approach are transition metal free, easy to operate, and all the starting materials are commercially available.
