1-Boc-4-amino-4-piperidineacetic acid

1-Boc-4-amino-4-piperidineacetic acid can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical production process.

A mixture of 4-oxo-piperidine- 1 -carboxylic acid tert-butyl ester (3.5 g, 17.55 mmol) (Sigma- Aldrich), malonic acid (2.0 g, 19.30 mmol) and ammonium acetate (3.1 g, 40.36 mmol) in n-BuOH was refluxed for 3 h. After cooled, white solid was collected, rinsed with EtOAc and dried in vacuo to provide the title compound 1.61 g (6.2 mmol) in 36% yield.
