A copper-catalyzed radical methylation/sp3 C-H amination/oxidation reaction for the facile synthesis of quinazolinone was developed. In this cascade reaction, dicumyl peroxide acts not only as a useful oxidant but also as an efficient methyl source. Notably, a methyl radical, generated from peroxide, was confirmed by electron paramagnetic resonance for the first time.
Stannous chloride in alcohol: A one-pot conversion of 2-Nitro-N- arylbenzamides to 2,3-Dihydro-1H-quinazoline-4-ones

A novel one-step synthesis of 2,3-dihydro-1H-quinazolin-4-ones from 2-nitrobenzamides is reported. These reactions are mediated by stannous chloride in 0.02 M methanolic or ethanolic HCl solution and proceed in good yields.
