Procedure
A mixture of tert-butyl 4-(but-3-en-1-yl)-4-methylpiperidine-1-carboxylate (3.5 g, 13.81 mmol) and 4M HCl/dioxane (17.27 ml, 69.1 mmol) was stirred at room temp for 3 h. Mixture was then concentrated and dried under high vac to afford 4-(but-3-en-1-yl)-4-methylpiperidine.HCl (2.6 g, 13.70 mmol, 99% yield) as off-white solid. 1H NMR (500 MHz, DMSO-d6) δ 5.83 (ddt, J=17.0, 10.3, 6.6 Hz, 1H), 5.05 (dq, J=17.1, 1.7 Hz, 1H), 5.00-4.80 (m, 1H), 3.11-2.90 (m, 5H), 2.05-1.90 (m, 2H), 1.56-1.42 (m, 5H), 1.38-1.26 (m, 2H), 0.95 (s, 3H). LCMS (M+H)=154.1.
