実験手順
The catalytic reduction was carried out in the same manner as in Example 1 except that the water-containing acetic acid was employed in an amount of 3 times (Example 15) or 8.8 times (Example 16) the weight of 4-hydroxymandelic acid. The yields of 4-hydroxyphenylacetic acid were 78% by mole (Example 15) and 95% by mole (Example 16).
