The procedure of Example 1 was repeated, except that the 1-ethynyl-4-(2-fluorophenyl)benzene was replaced with 23.1 g of 4'-(2-chlorophenyl)acetophenone, the amount of benzene was increased to 150 ml, the amount of catalyst was increased to 3 g, the amount of sulfuric acid was increased to 2 ml, and the reduction was allowed to proceed for 13 hours. Evaporation of the benzene left a residue which was vacuum distilled to give 14 g of 1-ethyl-4-(2-chlorophenyl)benzene, bp 110°-112°/0.4 mm. The following elemental anaylsis was obtained:
