Procedure for obtaining new heterocyclic derivatives, that is, the phenyldiazoaminophenanthridinium salts that respond to the formula **(See formula)** wherein R1 represents a substituted phenyldiazoamino radical (excluding an amidinophenyldiazoamino radical) or an amino radical and R2 represents a substituted phenyldiazoamino radical (excluding an amidinophenyldiazoamino radical) an amino radical or a hydrogen atom, one representing at least one of the expressed radicals R1 and R2 it is obligatory a phenyl diazoamino radical, R3 represents an aryl or substituted aryl alkoyl radical comprised therein, phenyl, p-aminophenyl and p-nitrophenyl, R4 represents an alkoxy radical (preferably lower alkoxy, that is, containing not more than 6 carbon atoms) and Y represents an anion, said process being characterized by diazotizing a suitable substituted aniline and coupling the appropriate molecular proportion of the resulting diazonium salt with a phenanthridinium salt of the general formula **(See formula)** where R5 represents an amino radical and R6 an amino radical or a hydrogen atom and R3, R4 and Y have the aforementioned meanings.
