Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure allows for selective modifications at the piperidine ring, making it valuable in medicinal chemistry for creating analogs with improved potency and selectivity. Commonly employed in the preparation of kinase inhibitors and receptor modulators due to the stability and steric properties provided by the tert-butyl and ethyl groups. Also utilized in research settings for building complex heterocyclic systems in drug discovery programs.
