Versuchsvorschrift

A solution of 2-hydroxy-3-methoxybenzaldehyde (6.08 g), ethyl bromoacetate (4.9 ml) and potassium carbonate (12.14 g) in N,N-dimethylformamide (30 ml) was stirred for 2 hours at ambient temperature. Water was added to the reaction mixture, and the resulting precipitates were collected by filtration and recrystallized with ethanol to give 2-ethoxycarbonylmethoxy-3-methoxybenzaldehyde (5.04 g).
