A Direct and General Synthesis of 5-Substituted 3-Trifluoromethyl-1,2,4-triazoles via the Three Component Condensation Reaction of Ethyl Trifluoroacetate,Hydrazine and Amidines
The three component condensation reaction of ethyl trifluoroacetate, hydrazine and amidines in the presence of sodium hydroxide in tetrahydrofuran at reflux temperature gave the corresponding 3-trifluoromethyl-5-substituted 1,2,4-triazoles in good to excellent yields.
