Procedure

A mixture of 4-[[2-(4-methylphenoxy)ethyl]oxy]-alpha-oxobenzeneacetic acid methyl ester (0.68 g) in methanol and 0.5N sodium hydroxide (8 mL) was treated as in Example 19. Extraction provided solids which were crystallized from diethyl ether-hexane to give 0.6 g of colorless 4-[[2-(4-methylphenoxy)ethyl]oxy]-alpha-oxobenzeneacetic acid, mp 135-136° C.
