Reaction Steps

A solution of methyl 3-[4-hydroxyphenyl)propionate (30.0 g, 0.166 mol), 2,2′-thiodiethanol (61.0 g, 0.50 mol) and triphenylphosphine (48.0 g, 0.183 mol) in dry benzene (450 ml) was treated at 22° C. with diethyl azodicarboxylate (33.2 g, 0.19 mol) added dropwise over 10 min and the resulting mixutre was stirred at 22° C. for 5 h. The reaction mixture was then diluted with ether (300 ml) washed with water, saturated sodium bicarbonate and brine. After drying (magnesium sulfate) the solvent was evaporated in vacuo and the residue was chromatographed on silica gel (elution toluene-ethyl acetate 85:15) to give 37.64 g (79%) of the starting material as a white solid: mp 47-48° C.
