Procedure

A mixture of alpha-oxo-4-(2-phenoxyethoxy)benzeneacetic acid methyl ester (1.6 g) in methanol (10 mL) and 0.5N sodium hydroxide (30 mL) was treated as in Example 19. Extraction provided solids which were crystallized from diethyl ether-hexane to give 1.4 g of colorless alpha-oxo-4-[[2-(phenoxy)ethyl]oxy]benzeneacetic acid, mp 102°-103° C.
