실험 절차

Following the procedure of Example 1, Part B, but substituting 21.76 gm. (0.0715 mole) of the dimethyl ester of 4-cyano-4-(o-tolyl)pimelic acid (prepared in Part A, above) for the 34.97 gm. of the dimethyl ester of 4-(p-chlorophenyl)-4-cyanopimelic acid and using 460 ml. of the tetrahydrofuran, 16.3 gm. (0.145 mole) of the potassium tert-butoxide, and 115 ml. of the 2.5 N aqueous acetic acid instead of the 700 ml., the 24.4 gm. and the 175 ml., respectively, there is prepared 18.0 gm. (93% yield) of 2-carbomethoxy-4-cyano-4-(o-tolyl)cyclohexanone as a crystalline solid having a melting range at 107° to 113° C.
