Reaction Steps

A stirred mixture of 4-hydroxy-alpha-oxobenzeneacetic acid methyl ester (0.724 g) in dimethylforrnamide (10 mL) under argon was treated with 55% sodium hydride (0. 175 g), stirred for 15 minutes and treated with the mesylate of 2-(4-nitrophenoxy)ethanol (1.56 g). The mixture was heated at 60° C. overnight and worked up as in Example 20. The material was purified by HPLC (dichloromethane-hexane; 9:1) and crystallized from dichloromethane-hexane to provide 0.75 g of 4-[[2-(4-nitrophenoxy)ethyl]oxy]-alpha-oxobenzeneacetic acid methyl ester as a 4:1 molar hydrate, mp 122°-123° C.
