HCID 21283773ethyl N-(o-trifluoromethyl-benzoyl)-o-chlorobenzimidate

Procedure

Analogously to the procedure described in Example 2, starting from ethyl o-chlorobenzimidate and o-trifluoromethyl-benzoyl chloride there is obtained ethyl N-(o-trifluoromethyl-benzoyl)-o-chlorobenzimidate, m.p. 64°-65° C., and therefrom by means of 2-hydroxyethylhydrazine there is obtained 3-(o-chlorophenyl)-1-(2-hydroxyethyl)-5-(o-trifluoromethyl-phenyl)-1H-1,2,4-triazole, m.p. 115° C.
