A mixture of alpha-oxo-4-[[(phenoxy)methyl]oxy]benzeneacetic acid methyl ester (0.43 g) in methanol and 0.5N sodium hydroxide (4 mL) was treated as in Example 19. Extraction provided 0.415 g which solidified and was crystallized from benzene-hexane to give 0.32 g of colorless alpha-oxo-4-[[(phenoxy)methyl]oxy]benzeneacetic acid as an 0.2 molar hydrate, mp 72°-74° C.
