실험 절차
1H-NMR (CDCl3,ppm) δ: 1.36-1.82(20 H,m), 2.36-2.88(4 H,m), 2.60-2.67(2 H,m), 2.97(2 H,t,J=7.3 Hz), 3.14(2 H,d,J=6.6 Hz), 5.01(1 H,br), 7.42-7.59(3 H,m), 7.93-7.97(2 H,m) (2) 4-Hydroxy-1-(6-oxo-6-phenylhexyl)-4-tert-butoxycarbonylaminomethylpiperidine (3.6 g) was dissolved in isopropyl alcohol (30 ml) and 15% hydrochloric acid-isopropyl alcohol (10 ml) was added under ice-cooling, which was followed by stirring at 60° C. for 3 hr. The solvent was evaporated under reduced pressure to give 2.92 g of 4-aminomethyl-4-hydroxy-1-(6-oxo-6-phenylhexyl)piperidine dihydrochloride.
