STUDIES ON PHENOTHIAZINES. PART 10 : SYNTHESIS OF 1-ETHOXY-7-SUBSTITUTED PHENOTHIAZINES
Gupta, Radha Raman,Kumar, Rakesh
, p. 1169 - 1173 (2007/10/02)
Synthesis of 1-ethoxy-7-substituted phenothiazines via Smiles rearrangement is reported. 2-Amino-3-ethoxybenzethiol was condensed with halonitrobenzenes and the substituted diphenylsulphides, so obtained, were converted into substituted formyl derivatives
