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-phenylthioethanol (1.16 g). The mixture was heated at 60° C. for five hours and worked up as in Example 20. The material was purified by HPLC (dichloromethane-hexane; 4:1) and crystallized from diethyl etherhexane to provide 0.5 g of alpha-oxo-4-[[2-(phenylthio)ethyl]oxy]benzeneacetic acid methyl ester, mp 49°-51° C.
