Following the procedure of Example 1, Part C, but substituting 44.7 gm. (0.174 mole) of 2-carbomethoxy-4-cyano-4-phenylcyclohexanone (prepared as in Part B, above) for the 29.8 gm. of the 2-carbomethoxy-4-(p-chlorophenyl)-4-cyanocyclohexanone and using 1200 ml. of the glacial acetic acid, and 600 ml. of the 10% aqueous sulfuric acid instead of the 660 ml. and the 330 ml., respectively, and finally recrystallizing the residual solid from a mixture of ethyl acetate and hexane, there is obtained 25.75 gm. (75% yield) of the desired 4-cyano-4-phenylcyclohexanone having a melting range from 112° to 115.5° C.
