Reaktionsschritte
Powdered potassium carbonate (5 g) was added to a solution of 3-hydroxybenzaldehyde (3.1 g, 25 mmol) and methyl bromoacetate (4.6 g, 30 mmol) dissolved in acetone (40 mL), and the mixture was stirred under reflux for 4 hours. The reaction mixture was then poured into excess water, extracted with dichloromethane, and evaporated. The resultant yellow oil was distilled on the Kugelrohr (1 mmHg, 150° C.) to give (3-formylphenoxy)acetic acid methyl ester as a colorless oil (4.53 g, 93%).
