Versuchsvorschrift

By the method of Example 1, Step H, 8,27 g (0.060 mole) of 4-methylsalicylaldehyde (Example 1, Step G) and 11.15 g (0.073 mole) of methyl bromoacetate were reacted in the presence of 10.1 g (0.073 mole) of anhydrous potassium carbonate in 150 mL of acetone, yielding 11.47 g of methyl (2-formyl-5-methylphenoxy)acetate as a white solid, m. p. 63°-64° C. The NMR was consistent with the proposed structure.
