Reaction Steps
In the same manner as in Reference Example 3, except that an equimolar amount of 3-octyloxy-4,5-dihydroxy-2H-1-benzopyran-2-one was used in place of 3-hexyloxy-4,5-dihydroxy-2H-1-benzopyran-2-one, and ethyl 3-bromopropionate was used in place of ethyl bromoacetate in Reference Example 3, 3-octyloxy-4-hydroxy-5-(2-ethoxycarbonylethoxy)-2H-1-benzopyran-2-one was obtained.
