Procedure
A mixture of 4-[[2-(1-naphthalenyloxy)ethyl]oxy]-alpha-oxobenzeneacetic acid methyl ester (0.7 g) in methanol and 0.5N sodium hydroxide (6 mL) was treated as in Example 19. Extraction with dichloromethane provided material which was crystallized from dichloro-methane-diethyl ether to give 0.54 g of colorless 4-[[2-(1-naphthalenyloxy) ethyl]oxy]-alpha-oxobenzeneacetic acid, mp 124°-125° C. after drying over phosphorus pentoxide at 60° C. and 0.1 mm.
