| | 4-Amino-1-benzylpiperidine Usage And Synthesis |
| Chemical Properties | clear colourless to light yellow liquid | | Uses | 4-Amino-1-benzylpiperidine was used in the preparation of:
- butyl 4-amino-1-piperidineacetate, key intermediate required for the synthesis of butyl 4-[(4-amino-5-chloro-2-methoxybenzoyl)amino]-1-piperidineacetate
- 5-alkylimino-1,2,4-thiadiazolidine-3-ones, such as 4-ethyl-5-[imino-[1-(phenylmethyl)-4-piperidinyl]]-2-methyl-1,2,4-thiadiazolidin-3-one and 4-benzyl-5-[imino-[1-(phenylmethyl)-4-piperidinyl]]-2-isopropyl-1,2,4-thiadiazolidin-3-one
- glycyrrhetinic acid derivatives
| | Purification Methods | Purify 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]. |
