Synthesis of 7-ethoxy- and 7-fluoro-phenothiazines
摘要:
Synthesis of 7-ethoxy- and 7-fluoro-phenothiazines is reported by Smiles rearrangement of 5-ethoxy- and 5-fluoro-2-formamido-2'nitrodiphenylsulfides. The later were obtained by the formylation of 2-amino-5-ethoxy/5-fluoro-2'-nitrodiphenylsulfides which were prepared by the condensation of 2-amino-5-ethoxyl-5-fluoro-benzenethiols with o-halonitrobenzenes.
