Reaction Conditions

Reaction Steps

A stirred mixture of 4-hydroxy-alpha-oxobenzeneacetic acid methyl ester (0.724 g) in dimethylformamide (10 mL) under argon was treated with 55% sodium hydride (0.175 g), stirred for 15 minutes and treated with the mesylate of 2-(3,4,5-trimethoxyphenoxy)ethanol (1.8 g). The mixture was heated at 60° C. overnight and worked up as in Example 20. The material form dichloromethane extraction was purified by HPLC (dichloromethane-diethyl ether, 50:1) and crystallized from dichloromethane-hexane to provide 1 g of 4-[[2-(3,4,5-trimethoxyphenoxy)ethyl]oxy]-alpha-oxobenzeneacetic acid methyl ester, mp 82°-83° C. Analysis Calculated for C20H22O8 : C, 61.53; H, 5.68. Found: C, 60.82; H, 5.71.
