Participants

Reaction Conditions

Reaction Steps

A mixture of commercially available 2,3-difluoro-6-hydroxybenzaldehyde (3.000 g; 21.40 mmol), iodoethane (6.679 g; 42.80 mmol), and K2CO3 (3.551 g; 25.70 mmol) in anh. DMF (60 ml) was heated to 80° C., under nitrogen, for 1.5 h. Et2O was added and the organic layer was washed with water, dried over anh. MgSO4, filtered, and concentrated to dryness under reduced pressure affording 6-ethoxy-2,3-difluorobenzaldehyde as a yellow solid. LC-MS (conditions A): tR=0.72 min.; no ionisation.
