실험 절차
2-Ethylpyridine (20.0 g, 186.65 mmol) was placed in carbon tetrachloride (830 mL) and benzoyl peroxide (4.5211 g, 18.665 mmol) and 1-bromopyrrolidine-2,5-dione (33.221 g, 186.65 mmol) were added. The reaction mixture was heated to reflux for 18 hours, then cooled to room temperature and filtered. The filtrate was concentrated and the residue was purified over a plug of silica to give 2-(1-bromoethyl)pyridine (17.312 g, 49.9%). 1H NMR (CDCl3) δ 8.58 (d, 1H), 7.69 (td, 1H), 7.76 (d, 1H), 7.20 (dd, 1H), 5.24 (q, 1H), 2.08 (d, 3H)
