An improved and facile preparation of tyramine [2‐(p‐hydroxyphenyl)ethylamine] was described, which starts from phenol and acrylonitrile to form β‐(p‐hydroxyphenyl) propionic acid via Friedel‐Craft's alkylation and nitrile hydrolysis. After hydrazinolysis and a subsequent Curtius rearrangement, tyramine was obtained in 30.2% total yield.
