Versuchsvorschrift

Following the procedure of Example 1, Part E, but substituting 17.54 gm. (0.058 mole) of 4-cyano-4-(3,4-dimethoxyphenyl)cyclohexanone, ethylene ketal (prepared in Part D, above) for the 21.87 gm. of 4-(p-chlorophenyl)-4-cyanocyclohexanone, ethylene ketal; and using 17.5 gm. (0.31 mole) potassium hydroxide and 175 ml. ethylene glycol instead of the 22.0 gm. and 220 ml., respectively; there is obtained, after removal of the ether, 19.0 gm. (99% yield) of 4-carboxy-4-(3,4-dimethoxyphenyl)cyclohexanone, ethylene ketal as a gum that gives a reasonably expected infrared spectrum.
