4-Benzylpiperidine

4-Benzylpiperidine is a drug and research chemical used in scientific studies. It acts as a monoamine releasing agent with 20- to 48-fold selectivity for releasing dopamine versus serotonin. It is most efficacious as a releaser of norepinephrine, with an ec50 of 109/41.4/5246nM for DA/NE/5HT, respectively .[1] It has a fast onset of action and a short duration.[1] It also functions as a monoamine oxidase inhibitor (MAOI) with preference for MAO-A.[2]

Synthesis

4-Cyanopyridine can be reacted with toluene to give 4-benzylpyridine.[3] Catalytic hydrogenation of the pyridine ring then completes the synthesis.
