Abstract
Improvements introduced in the object of main patent no. 381.402, filed on July 3, 1970, by: Procedure for obtaining basically substituted derivatives of 2,4- (1H, 3H) -quinazolinedione, of general formula **(See formula)** where R'means a residue linked via a nitrogen atom, a secondary aliphatic, cycloaliphatic, araliphatic amine with 2 to 10 carbon atoms, or a heterocyclic nitrogen base with 5, 6 or 7 members, which in the ring, in addition to the nitrogen atom, contains a corresponding number of methylene groups, as well as, optionally, another nitrogen atom, an oxygen atom or a sulfur atom; R1 means a lower alkoxy group with 1 to 4 carbon atoms, which may preferably be in positions 6, 7 or 6, 7, 8; R2 means an alkoxy radical with 1 to 4 carbon atoms; m represents the numbers 1, 2 or 3; and n means the numbers 2 or 3; characterized in that (1H, 3H) -quinazolin-2-thion-4-one of general formula: **(See formula)** in which R1 has the meaning indicated above, R = R', or in the case that R' contains an acyloxy moiety of general formula: **(See formula)** It can also mean the rest of the hydroxy compound on which it is based, is acylated with an alkoxybenzoic acid of the general formula: **(See formula)** or a functional derivative thereof, optionally in the presence of an acid acceptor.
