Zur Kernacylierung von 1‐Methylphenothiazin. 7. Mitt.: Über Phenothiazinverbindungen

Abstract: 1‐Methyl‐10‐acetylphenothiazin liefert in einer Friedel‐Crafts‐Reaktion 1‐Methyl‐2,10‐diacetylphenothiazin. Die Struktur dieser Verbindung wird aufgeklärt. 1‐Methyl‐2‐acetylphenothiazin wird nach Wolff‐Kishner zu 1‐Methyl‐2‐äthylphenothiazin reduziert, aus dem durch Desulfurierung mit Raney‐Nickel 2‐Methyl‐3‐äthyl‐diphenylamin gewonnen wird. Die Synthese von 2,3‐Dimethyldiphenylamin und 1,2‐Dimethylphenothiazin wird beschrieben.
