IMPROVED SYNTHESES OF AMINOACRIDINES. PART IV. SUBSTITUTED 5-AMINOACRIDINES

by ADRIEN ALBERT and WALTER GLEDHILL

The reaction whereby 5-chloroacridine is converted into 5-aminoacridine in an open vessel with the aid of phenol and ammonium carbonate (Part 1) has been applied to twenty-four variously substituted 5-chloroacridines, many of which have proved to be powerful antibacterials. The reactions of 5-chloroacridine with ethanolamine and with ethylenediamine are also described.
