Microwave-assisted phenothiazines preparation by thionation of diphenylamines

Article abstract of DOI:10.1080/00397919808005727

A preparation in 'dry media' of phenothiazine derivatives by thionation of diphenylamines using microwave-activation is presented. This method allowed the preparation of 2,4,6,8-tetra-tert-butyl-10H-phenothiazine 2e, the first 2,4,6,8-tetra-substituted derivative of this heterocycle, practically inaccessible by other thionation procedure.
