Water → [2-Bromo-3,5-bis(methoxymethoxy)phenyl]methanol

Participants

Reaction Steps

The above-obtained 3,5-bis(methoxymethoxy)phenylmethanol (5.3 g, 23 mmol) was dissolved in N,N-dimethylformamide (20 mL) and obtained solution was added with N-bromosuccinimide (4.3 g, 24 mmol) followed by stirring at a room temperature for 5 hours. The reaction mixture was added with water and extracted with chloroform 3 times. The organic layers were combined, washed with saturated brine, dried over anhydrous sodium sulfate and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=9/1 to 5/1 to 2/1) to obtain [2-bromo-3,5-bis(methoxymethoxy)phenyl]methanol (4.9 g, 69%).
