実験手順

1-Carbethoxy-4-dimethylamino-3-methylpiperidine (3.5 g, 16.3 mmol) was suspended in 5 M NaOH solution (20 ml), stirred at 110° C. for 48 hr, cooled, extracted with ethyl acetate, dried (Na2SO4) and concentrated to dryness to afford 4-dimethylamino-3-methylpiperidine. Yield 1.0 g (43%), C8H18N2, m/z 143 (M+1), PMR (CDCl3): 0.96 (dd, 3H), 1.3 (m, 1H), 1.5 (m, 1H), 1.74 (m, 1H), 2.08 (m, 1H), 2.24 (s, 6H), 2.38 (m, 1H), 2.61 (bs, 1H, D2O exchangeable), 2.86 (m, 1H), 3.16 (m, 1H), 3.68 (m, 1H).
