実験手順
Subsequently, the resulting crude 1-(tert-butoxycarbonyl)-4-[(2-phthalimidylmethylphenyl)amino]piperidine (420 mg) was dissolved in ethanol (8 ml), added with hydrazine monohydrate (0.23 ml) and stirred at room temperature for 1 hour and at 40° C. for 1 hour. After insoluble matters were removed by filtration from the reaction mixture, the solvent was evaporated under reduced pressure. The residue was added with water (10 ml) and extracted twice with dichloromethane (10 ml). The solvent was evaporated under reduced pressure to obtain 219 mg of 1-(tert-butoxycarbonyl)-4-[(2-aminomethylphenyl)amino]piperidine.
