Abstract
Procedure for preparing quinazolinones, of general formula I, **(See formula)** where R signifies a hydrogen or halogen atom, R1 signifies a hydrogen atom, an alkyl radical containing 1 to 5 carbon atoms, an allyl radical or a propargyl radical, and R2 signifies the radical (see formula) in which Y means a hydrogen atom or an alkyl radical containing from 1 to 4 carbon atoms, characterized in that a compound of general formula VII is reacted, **(See formula)** wherein R, R1 and R2 have the meanings indicated above, with a C1-C5 lower alkyl carbamate in the presence of a catalytic amount of a Lewis acid.
