Reaction Steps

The acid chloride, prepared from 4-[[2-(2-naphthalenyloxy)ethyl]oxy]-alpha-oxobenzene-acetic acid (0.5 g) as described in Example 6, was dissolved in dichloromethane (10 mL) and added dropwise to a stirred, cold (<-50° C.) mixture of glycerine (0.9 mL) in tetrahydrofuran (10 mL). The cooling bath was removed and the mixture stirred for 1 hour at room temperature. The mixture was diluted with dichloromethane and washed once with saturated aqueous sodium bicarbonate, once with water, and the organic solution was dried (Na2SO4), filtered, and evaporated to give crude product. The material was purified by HPLC (ethyl acetate) to provide, after crystallization from ethyl acetate-hexane, 0.25 g of rac.-4-[[2-(2-naphthalenyloxy)ethyl]oxy]-alpha-oxobenzeneacetic acid 2,3-dihydroxypropyl ester as a colorless solid, mp 124°-125° C.
