Procedure
1-Boc-piperazine (4.0 g, 21.5 mmol), 4-vinylpyridine (2.94 g, 27.9 mmol), and acetic acid (1.29 g, 21.5 mmol) were mixed in ethanol and heated to reflux for 48 h. The mixture was cooled to room temperature and concentrated under vacuum to provide 1-Boc-4-[2-(4-pyridinyl)ethyl]-piperazine (2.9 g, 45%) as an off white solid. The product was used without further purification.
