3-溴-2-(2-甲氧基乙氧基甲氧基)苯甲醛

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 3-Bromo-2-hydroxybenzaldehyde (1.5 g, 7.5 mmol) was dissolved in dichloromethane (25 mL) and diisopropylethylamine (2 mL, 11.3 mmol) was added to the solution. The mixture was stirred while 2-methoxyethoxymethyl chloride (0.94 mL, 8.3 mmol) was added dropwise. The mixture was stirred for 1 hour and then washed with 5% citric acid solution (5 mL) until the washings were acidic, dried and concentrated by evaporation. Product was purified from the residue by chromatography (silica gel, 30% ethyl acetate/hexanes) to give 3-bromo-2-(2-methoxy-ethoxymethoxy)benzaldehyde (1.7 g). was added dropwise washed with 5% citric acid solution (5 mL) until the washings dried concentrated by evaporation Product was purified from the residue by chromatography (silica gel, 30% ethyl acetate/hexanes)
