Imidazolium chloride as an environmentally benign additive efficiently facilitates construction of 4(3H)-quinazolinones using anthranilamides and DMF derivatives. A series of 4(3H)-quinazolinones were prepared in moderate to excellent yields without conventional oxidants, metal catalysts and corrosive acids or other additives.
