Versuchsvorschrift
3-[4-(2-pyridyl)piperidin-1-yl]propylamine L-tartrate salt, (7), (1120 g, 3.0 mol) was treated with 5M NaOH (5.7 L, 28.6 mol). The suspension was extracted with isopropyl acetate (3×18 L). The combined extracts were concentrated to afford 3-[4-(2-pyridyl)-piperidin-1-yl]propylamine, (6), as a viscous oil.
