Stir 7.9 g of the title compound of Example 85 and 7.05 g of 4-chlorobenzylcyanide in 30 ml of benzene for 3 hours at 45°. Free the resulting reaction mixture from solvent by distillation to produce a dark-brown crystalline residue. Take up this residue with 10 ml of isopropanol and filter it to obtain 2.5 g of the title compound as yellowish crystals of m.p. 68° to 71°.
