Reaktionsschritte
The naphtholactam compounds of the formula (II) used as starting products are obtainable by reacting o-xylylenedicyanide with glyoxal in the presence of a base (NaOH, KOH) and of a solvent at temperatures below 50° C. (e.g. 0° to 40° C.) to give 1,4-dicyanonaphthalene, and subsequently either
