Abstract

Improvements introduced in the object of the main patent no. 266,515 granted on september 12, 1961, by "process for obtaining phenothiazine derivatives", preferably for the preparation of 3-methylmercapto-10- [2 "- (1" '' -methyl-piperidyl-2 "'") - ethyl-1 "' - phenothiazine of the formula i **figure** It is known that 3-methylmercapto-10- [2 "- (1" '' - methyl-piperidyl- (2 "'') - ethyl-1"] - phenothiazine of the formula i can also be obtained by cyclization of dithiohydroquinone derivatives in the presence of dimethyl formamide, an alkaline condensation medium, such as sodium or potassium carbonate, and some copper powder.the known process, however, provides only small yields, maximum 60-70%.
