A Versatile New Synthesis of Quinolines and Related Fused Pyridines. Part 11. Conversion of Acylanilides into α-Iminopyridines
The Vilsmeier formylation of enamidines, readily derived by treatment of acetanilides with PCl5, allowed the synthesis of 6-chloro-1-aryl-2-iminopyridines.Similarly other acylanilides (RCH2CONHAr) gave 3,5-R2 disubstituted analogues.
