4-Amino-1-benzylpiperidine Usage And Synthesis
  • Chemical Propertiesclear colourless to light yellow liquid
  • Purification MethodsPurify it by distillation in vacuo and store it under N2 because it absorbs CO2. The dihydrochloride salt [1205-72-7] has m 270-273o (255o) after recrystallisation from MeOH/EtOAc or EtOH. [Brookes J Chem Soc 3165, 3172 1957.] The 4-methylamino-1-benzylpiperidine derivative has b 168-172o/17mm, nD 1.5367 [Reitsema & Hunter J Am Chem Soc 70 4009 1948]. The 1-(1-benzyl-4-piperidinyl)-3-cyano-2-methylisothiourea derivative has m 160o from CHCl3/Et2O [Preparation, IR, NMR: Ried et al. Chem Ber 116 1547 1983, Beilstein 22 III/IV 3752].
