Versuchsvorschrift
A mixture of 4-[[2-(4-chlorophenoxy)ethyl]oxy]-alpha-oxobenzeneacetic acid methyl ester (0.72 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 0.63 g of colorless 4-[[2-(4-chlorophenoxy)ethyl]oxy]-alpha-oxobenzeneacetic acid, mp 121°-122° C.
