Reaction Steps

3-Bromo-3-phenylpyridine (200 mg, 0.85 mmol) was dissolved in Et2O and cooled to -30° C. A solution of 2.5M t-BuLi (1.1 mL, 1.90 mmol) in pentane was added, and the reaction was stirred for 10 minutes. 1,2,3,5,6,7-Hexahydropyrrolizinium perchlorate (230 mg, 1.30 mmol) was added, and the reaction mixture was allowed to stir for 30 minutes at -30° C. then allowed to warm to room temperature and stir for 1 hour. Then 2N HCl was added, the phases were separated, and the aqueous phase was basified with 15% NaOH and extracted with CH2Cl2 (2×). The organic phases were combined, dried (MgSO4) and concentrated, and the residue was chromatographed (silica gel; CHCl3 /MeOH, 95:5) to afford a clear oil (32.5 mg).
