Abstract

The invention comprises the preparation of compounds of general formula <FORM:1019112/C2/1> wherein X is -CH2-or-CO-, and <FORM:1019112/C2/2> is a disubstituted amino radical with aliphatic hydrocarbon residues or a cyclic imine radical with or without an oxygen atom, sulphur atom or further nitrogen atom in the ring, by reacting 3-phenyl-6-pyridazone with a compound <FORM:1019112/C2/3> Hydrochlorides are obtained also.
