ABSTRACT:
A process for producing an dioxoquinazoline of following formula (II): ##STR1## wherein R.sub.1 and R.sub.2 independently represent a hydrogen atom, a halogen atom, a nitro group, a lower alkyl group, an aralkyl group, an alkoxy group, an alkoxylcarbonyl group or a group represented by YNR.sub.3 R.sub.4, wherein Y represents a direct bond, a lower alkylene group or a carbonyl group, and R.sub.3 and R.sub.4 independently represent a lower alkyl group or N, R.sub.3 and R.sub.4 may bond together to form a five- or six-membered heterocycle which comprises reacting an anthranylamide of formula (I): ##STR2## wherein X, R.sub.1 and R.sub.2 are as defined above.
