A solution of 9.25 g of 1-(1,1-diethoxyethyl)-1,2,4-triazole in 150 ml of ether was treated first with 38.5 ml of 1.3M n-butyllithium in hexane and then with 12.6 g of 4,4'-dichlorobenzophenone in the same manner as Exaample 1. The mixture was added to ice and hydrochloric acid producing a white suspension which was recovered by filtration. The solid was recrystallized from 600 ml of methanol/200 ml of water to provide 11.52 g of the desired title product, m.p. 233°-234° C.
