(0.0951 mole) of the dimethyl ester of 4-(m-anisyl)-4-cyanopimelic acid (prepared in Part a, above) for the 34.97 gm. of the dimethyl ester of 4-(p-chlorophenyl)-4-cyanopimelic acid and using 620 ml. of the tetrahydrofuran, 21.3 gm. (0.19 mole) of the potassium tert-butoxide, and 150 ml. of the 2.5 N glacial acetic acid instead of the 700 ml., the 24.4 gm. (0.218 mole), and the 175 ml., respectively, there is prepared 29.1 gm. (99% yield) of 4-(m-anisyl)-2-carbomethoxy-4-cyanocyclohexanone as a gum.
