Reaction Steps

A solution of 2-(3-bromophenyl)pyridine (2.4 g, 10.25 mmol) in anhydrous tetrahydrofuran (25 mL) was stirred at −78° C. and 2.5M n-butyllithium in hexanes (4.1 mL, 10.25 mmol) was added at such a rate that temperature did not exceed −70° C. Stirring was continued on the cold bath for 30 min and a solution of 2-(benzyloxy)-3-tert-butylbenzaldehyde (2.75 g, 10.25 mmol) in tetrahydrofuran (12 mL) was added at such a rate that temperature did not exceed −65° C. Stirring was continued on the cold bath for 20 min and 2 hr at room temperature. The reaction mixture was poured on saturated ammonium chloride (250 mL) and extracted with ethyl acetate (350 mL). The organic extract was washed with water (2×100 mL) and dried over sodium sulfate. The solvent was removed on a rotary evaporator and the crude product was used as such in the next step.
