Participants

Reaction Conditions

Reaction Steps

To a solution of 2-bromo-5-hydroxybenzaldehyde (5 g, 24.87 mmol) in DMF (20 mL) was added iodoethane (5.82 g, 37.3 mmol) and K2CO3 (6.88 g, 49.7 mmol) portion wise. The resulting reaction mixture was stirred at 50° C. overnight. After cooling, the mixture was diluted with EtOAc/hexanes (1:1) and water. Layers were separated and the organic layer was washed with brine, dried over sodium sulfate, filtered and concentrated to give the title intermediate (4.6 g) as white solid.
