A mixture of commercially available 2-chloro-6-hydroxybenzaldehyde (2.000 g; 12.80 mmol), iodoethane (3.985 g; 25.50 mmol), and K2CO3 (2.119 g; 15.30 mmol) in anh. DMF (35 ml) was heated to 80° C., under nitrogen, for 1 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 2-chloro-6-ethoxybenzaldehyde as a yellow solid. LC-MS (conditions A): tR=0.75 min.; [M+H]+: 185.39 g/mol.
