Reaction Steps

A mixture of 2-(3,4-dimethylphenylthiomethyl)glutaric acid (1.16 g), methanol (20 ml), and p-toluenesulfonic acid (0.04 g) was stirred at 40° C. for 1.5 hours. The reaction mixture was concentrated in vacuo, and the residue was purified by flash column chromatography on silica by eluting with chloroform/ethanol (10:1) to give 0.98 g of 3-(3,4-dimethylphenylthio)-2-(2-methoxycarbonylethyl)propionic acid as an oil.
