Versuchsvorschrift
In the same manner as in Reference Example 1, 5-methoxysalicylaldehyde was reacted with methyl bromoacetate to yield methyl 2-formyl-4-methoxyphenoxyacetate (yield 86%), which was then recrystallized from acetone-hexane to yield colorless prisms having a melting point of 74° to 75° C.
