실험 절차

In the same manner as in Reference Example 3, except that an equimolar amount of 3-hexyloxy-4,8-dihydroxy-2H-1-benzopyran-2-one was used in place of 3-hexyloxy-4,5-dihydroxy-2H-1-benzopyran-2-one, and ethyl 3-bromobutanoate was used in place of ethyl bromoacetate in Reference Example 3, 3-hexyloxy-4-hydroxy-8-(3-ethoxycarbonylpropyloxy)-2H-1-benzopyran-2-one was obtained.
