Reaction Steps

To a solution of 1-(4-bromophenyl)cyclopropanecarbonitrile (2.01 g, 0.00905 mol) in tetrahydrofuran (30 mL, 0.4 mol) was added 2.5 M of n-butyllithium in hexane (4.0 mL) at −78° C. and the mixture was stirred at −30° C. for 30 minutes. A solution of cyclopentanecarbaldehyde (0.972 g, 0.00990 mol) in THF (2 mL) was added to the above mixture and the resulting mixture was stirred at −78° C. for 2 hours. The reaction was then quenched with a small amount of saturated aqueous NH4Cl solution followed by extraction with ethyl acetate, drying with MgSO4, and concentrating under reduced pressure. The crude product was purified by flash chromatography, eluting with 30% AcOEt in hexanes.
