Abstract:
A series of novel substituted 4‐trifluoromethyl‐pyridin‐2‐yl hydrazide derivatives 5 and 7‐trifluoromethyl‐1,2,4‐triazolo[4,3‐a]pyridine derivatives 6 were synthesized through a facile method in single step from 2‐hydrazino‐pyridine derivatives 4 and their reaction with aliphatic/aromatic acids in the presence of POCl 3 and PCl 5 . In each reaction, an intermediate 5 and product 6 were formed in definite proportion except in 5a , 5d , and 6e and were independent of reaction time and temperature.
