Abstract

Procedure for the preparation of new pyrido [3,2-d] pyrimidines of the general formula I, **(See formula)** in which one of the radicals R1 or R2 means the piperazine radical and the other of the radicals R1 or R2 represents a morpholino, thiomorpholino, 1-oxidothiomorpholino, 1,1-dioxidothiomorpholino or piperidino radical, possibly substituted by a lower alcohol radical, a piperazino radical optionally substituted in position 4 by a carbamoyl or lower alcohol radical, a dialkanolamino or alcohol-diamine amino group; and R3 signifies a hydrogen atom or the methyl group, as well as its physiologically compatible acid addition salts, characterized in that a compound of the general formula II is deacylated. **(See formula)** where R3 is as initially defined, one of the radicals R4 or R5 represents a piperazine radical substituted in position 4 by an acyl radical and the other of the radicals R4 or R5 has the initially mentioned meanings for R1 or R2; and, in case a compound of the general formula I is obtained, in which R1 and/or R2 represent free piperazine groups, these are subjected, if desired, to carbamoylation and/or a compound obtained from the general formula I is transformed, if desired, in its physiologically compatible salts with organic or inorganic acids.
