Procedure

In the same manner as in Reference Example 1, except that an equimolar amount of 3-butoxy-4,8-dihydroxy-2H-1-benzopyran-2-one was used in place of 3-ethoxy-4,5-dihydroxy-2H-1-benzopyran-2-one, and 3-bromopropyl acetate was used in place of 2-bromoethyl acetate in Reference Example 1, 3-ethoxy-4-hydroxy-8-(3-acetoxypropyloxy)-2H-1-benzopyran-2-one was obtained.
