Reaction Steps

A solution of KOH pellets (85%, 0.68 g, 10.3 mmol) in water (1.5 mL) was added to 2-bromophenol (1 mL, 8.6 mmol). The mixture was diluted with DMSO (20 mL) and bromoacetaldehyde diethyl acetal (1.43 mL, 9.5 mmol) was added. The mixture was heated at 100° C. for 6 h, cooled to rt, diluted with ether (175 mL), washed with water (3×40 mL) and 5% aq NaOH (40 mL), and dried over MgSO4. Removal of the solvent left 1-(2,2-diethoxyethoxy)-2-bromobenzene (2.62 g, quant) as an oil.
