Reaktionsschritte
Toluene (3.5 mL) was added to a 3-necked flask and cooled to −60° C. n-BuLi (1.3 mL, 2.5M in hexanes) was added. A solution of 3-bromopyridine (0.3 mL, 3 mmol) in toluene (1.2 mL) was added dropwise to maintain internal temperature <−50° C. The resulting slurry was then stirred for 30 minutes at −60° C. THF (1.2 mL) was added dropwise, and the mixture was stirred for an additional 15 minutes. 4-Chloro-2-methoxy-benzaldehyde (561 mg, 3.3 mmol) was added and the mixture was allowed to warm to room temperature. The reaction was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried (MgSO4), filtered, and concentrated under vacuum. The residue was purified by flash column chromatography on silica gel with 7:3 hexanes/ethyl acetate to provide 201 mg (27%) of the title compound. MS (ESI) m/e 250 (M+H)+.
