Procedure
A mixture of 1.1 g of 3-(o-chlorophenyl)-1-(2-hydroxyethyl)-5-(o-trifluoromethyl-phenyl)-1H-1,2,4-triazole, 1.09 g of thionyl chloride and 5 ml of toluene is heated at reflux temperature for 4 hours. The reaction mixture is then evaporated, the residue is taken up in diethyl ether, the soluton is washed twice with 5% sodium bicarbonate solution, dried over anhydrous magnesium sulphate and evaporated. In this manner there is obtained 1-(2-chloroethyl)-3-(o-chlorophenyl)-5-(o-trifluoromethyl-phenyl)-1H-1,2,4-triazole, m.p. 66°-68° C.
