Abstract:N-Boc-1,2,3,5-tetrahydro spiro[benzo[c]azepine-4,2-piperidine] was synthetized using1-Boc-piperidine-2-carboxylic acid metyl ester and 2-bromomethyl - benzonitrile as the raw materials followed by nucleophilic substitution reaction, cyano-reduction reaction, and cyclization reaction. The chemical structure of this novel compound was characterized using 1H NMR, 13C NMR and High Resolution Mass Spectrometry, and a yield of 48% was obtained.
Key words:benzonitrile; cyano reduction; piperidine
