YieldReaction ConditionsOperation in experiment
To a solution of <strong>[656-35-9]2,4-difluorophenylacetonitrile</strong> (3.0 g, 19 mmol) in anhydrous DCM (40 mL), cooled to -78 C., was added DIBAL (40 mL, 1 M in DCM) dropwise. The resulting mixture was allowed to warm to room temperature overnight. Excess reagent was quenched with ethyl formate (1.6 mL). After 1.5 h the mixture was poured into saturated NH4Cl (300 mL) then treated with 2 M H2SO4 (100 mL). The mixture was extracted with Et2O. The extracts were washed with water and saturated brine and dried (MgSO4). Toluene was added and solvent removed at <30 C. on high vacuum to a final volume of ~30 mL. The solution of the crude aldehyde, approx. 100 mg/mL, was used without further purification.
