実験手順
A mixture of 1.31 g (3.8 mmoles) of 2-[1-(2-phenylethyl)-4-piperidylmethyl]-1H-isoindole-1,3(2H)-dione dione (Example 2) and 0.25 mL (7.8 mmoles) of hydrazine in 20 mL of ethanol was heated under reflux for 4 hours. The solvent was removed and the residue was made basic with aqueous potassium hydroxide and extracted with chloroform to give 0.90 g of 1-(2- phenylethyl)-4-piperidinemethylamine as an oil. NMR (CDCl3): δ7.14-7.35 (m, 5H); 2.93-3.10 (d, 2H); 2.72-2.85 (m, 2H); 2.52-2.65(m, 4H); 1.92-2.05 (t, 2H); 1.61-1.87 (m, 2H); 1.08-1.48 (m, 5H) .
