摘要

Abstract N-alkylation of azaphenothiazines using dibromoalkanes or dibromoalkenes did not result in the formation of bis-azaphenothiazines under known conditions such as refluxing, for more than 100 h, with NaNH 2/xylene or NaH/toluene. However, when the same reaction was tried with NaH/DMF at− 5° C to rt, it yielded the desired product in 68– 71% yield. These novel bis-azaphenothiazines containing a suitable alkyl or alkenyl ...
