Reaction Conditions

Reaction Steps

To a chilled reaction vessel at −45° C. containing 1-benzyl-1H-imidazole (3.0 g, 19.0 mmol) in Et2O (100 mL) was added a solution of n-butyllithium (2.5M in hexanes, 10.8 mL, 26.9 mmol) dropwise. After 30 min, the reaction vessel was cooled to −78° C. and 2-ethylbutyraldehyde (2.8 mL, 22.8 mmol) was added dropwise. The reaction mixture was warmed to 0° C. and stirred for 15 min, then poured into sat. aqueous NH4Cl and extracted with Et2O. The organic layer was washed with H2O, dried over MgSO4, filtered and concentrated in vacuo. The resulting yellow oil was purified by column chromatography (SiO2, EtOAc/hexane, 3:2, then 7:3) to yield a clear oil in 69% yield.
