Procedure
The Mixture B of isomers of 1-carbethoxy-4-cyclopropylamino-3,5-dimethylpiperidine (2.8 g, 1.16 mmol) was stirred in a mixture 5 N NaOH solution (20 ml) and ethyl alcohol (5 ml) at 100° C. for 120 hr, cooled, extracted with ethyl acetate, dried (Na2SO4) and concentrated to afford Mixture B of isomers of 4-cyclopropylamino-3,5-dimethylpiperidine as an oil. Yield 1.6 g (84%), C10H20N2, m/z 169 (M+1) PMR (CDCl3): 0.82-1.05 (m, 10H), 1.5 (m, H), 1.75 (m, H,), 2.16-2.38 (m, 3H), 2.65 (m, 1H), 2.78 (m, 1H), 3.02 (m, 1H), 3.41 (m, 1H), 3.64 (m, 1H).
