실험 절차

Following the procedure of Example 1, Part B, but substituting 42.44 gm. (0.14 mole) of the dimethyl ester of 4-cyano-4-(p-tolyl)pimelic acid (prepared in Part A, above) for the dimethyl ester of 4-(p-chlorophenyl)-4-cyanopimelic acid and using 900 ml. of the tetrahydrofuran, 31.5 gm. (0.28 mole) of the potassium tert-butoxide, and 225 ml. of the 2.5 N aqueous acetic acid instead of the 700 ml., the 24.4 gm. (0.218 mole), and the 175 ml., respectively, there is prepared 39.3 gm. (99% yield) of 2-carbomethoxy-4-cyano-4-(p-tolyl)cyclohexanone as a gum.
