Photochemical irradiation of 2,3-dihydro-2-tert-butyl-3-benzyl-4(1H)- quinazolinone produced 3-benzyl-4(3H)-quinazolinone through photoinduced elimination via a radical mechanism. The use of photochemical conditions such as chloroform and UV irradiation (δ= 254 nm) got the 3-benzyl-4(3H)- quinazolinone in a high yield. Some theoretical calculations were achieved to explain the mechanism and the presence of radical intermediates was confirmed by trapping with different 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) derivatives.
