Following the procedure of Example 1, Part B, but substituting 53.94 gm. (0.169 mole) of the dimethyl ester of 4-cyano-4-(p-anisyl)pimelic acid (prepared in Part A, above) for the dimethyl ester of 4-(p-chlorophenyl)-4-cyanopimelic acid and usig 1100 ml. of the tetrahydrofuran, 38.0 ml. (0.34 mole) of the potassium tert-butoxide, and 270 ml. of the 2.5 N hydrochloric acid instead of the 700 ml., the 24.4 gm. (0.218 mole), and the 175 ml., respectively, there is prepared 46.2 gm.
