A mixture of 2,4-difluoro-6-hydroxybenzaldehyde (4.340 g; 27.50 mmol), iodoethane (8.562 g; 54.90 mmol), and K2CO3 (4.553 g; 32.90 mmol) in anh. DMF (75 ml) was heated to 80° C., under nitrogen, for 45 min. Et2O and water were added, and the organic layer was further washed with brine, dried over anh. MgSO4, filtered, and concentrated to dryness under reduced pressure affording 2-ethoxy-4,6-difluorobenzaldehyde as an orange solid. LC-MS (conditions A): tR=0.70 min.; [M+H]+: 187.39 g/mol.
