Reaction Steps
Diisopropylethylamine (21.8 mL, 151.5 mmol) was added slowly to a magnetically stirred solution of 3-bromo-4-hydroxybenzonitrile (10 g, 50.5 mmol) and 2-methoxyethoxymethyl chloride (6.9 mL, 60.6 mmol) in dichloromethane (100 mL) and the mixture was stirred at room temperature for 30 minutes. The mixture was washed with 5% citric acid solution until the washings were acidic, dried and concentrated. Product was purified from the residue by chromatography (silica gel, 30% ethyl acetate/hexanes) gave 3-bromo-4-(2-methoxyethoxymethoxy)-benzonitrile (11.5 g).
