Reaction Conditions

Reaction Steps

A solution of 3-bromobiphenyl (Aldrich; 1 molar eq.) in dry THF was cooled to −78° C. and treated with tert-butyllithium (Aldrich; 1.7 M in hexanes, 2 molar eq.) in a dropwise manner. The reaction was allowed to stir at −78° C. for 40 minutes. Dimethylformamide (Aldrich; 2.5 molar eq.) was added and stirring continued an additional 20 minutes. The mixture was partitioned in a separatory funnel between methylene chloride and water. The organic layer was dried over Na2SO4, filtered, and concentrated. The residue was purified via HPLC eluting with 5% ethyl acetate/hexanes. The desired aldehyde w as obtained in 71% yield.
