    Description / Table of Contents: Syntheses with Quinones in situ, VII 1). Preparation of 7-Dimethylamino-2-hydroxyphenothiazin-3-one7-Dimethylamino-2-hydroxyphenothiazin-3-one (4) is obtained for the first time by using 2-amino-5-dimethylanilin-thiosulfuric acid (1) as starting material. There are two different procedures, the second procedure allows the isolation of the intermediate indophenol.
