Abstract

Die vorliegende Erfindung beschreibt ein Verfahren zur Herstellung von 4-Amino-1-naphtholethern das dadurch gekennzeichnet ist, dass aus 1-Naphtholen zunächst Naphtholether hergestellt werden, diese dann in die entsprechenden 4-Acetamino-1-naphtholether überführt werden und danach die Acylgruppe abgespaltet wird. Bestimmte 4-Acetamino-1-naphtholether sind ebenfalls Bestandteil der Erfindung.
