Reaction Conditions

Reaction Steps

To a mixture of 3-hydroxy-4-difluoromethoxybenzaldehyde (19.55 g, 104 mmol) and potassium carbonate (21.56 g, 156 mmol) in dimethylformamide (150 mL) under an argon atmosphere at 60° C. was added bromomethylcyclopropane (15.13 mL, 156 mmol) and the mixture was stirred and heated at 65° C. After 1.5 h, the mixture was allowed to cool and was filtered. The filtrate was concentrated under reduced pressure and the residue was partitioned between ethyl acetate and water and was extracted four times with ethyl acetate. The organic extract was washed twice with water and was dried (sodium sulfate). The solvent was removed in vacuo to provide an oil (26.4 g).
