m-Chloroperbenzoic acid → Formic Acid 4-fluoro-3,5-dimethyl-phenyl ester

Participants

Reaction Conditions

Reaction Steps

To a solution of 4-fluoro-3,5-dimethyl-benzaldehyde (1.0 g, 6.4 mmol) in 20 mL DCM was added mCPBA (1.2 g, 7.6 mmol) at 25° C. After being stirred for 20 h at 25° C., the reaction was quenched by the addition of 40 mL of 5% aqueous potassium carbonate. The mixture was extracted DCM (3×30 mL) and the combined DCM layer was washed with brine (2×30 mL). The solution was dried over Na2SO4 before being concentrated under reduced pressure. The crude product was used directly in the next reaction without further purification.
