Reaction Steps
A mixture of 2-(3,4-dichlorophenylthiomethyl)glutaric acid (3.00 g), methanol (30 ml), and p-toluenesulfonic acid (0.09 g) was stirred at 40° C. for 2.5 hours. The reaction mixture was concentrated in vacuo, and the resulting residue was purified by flash column chromatography on silica by eluting with chloroform/ethanol (10:1) to give 2.92 g of 3-(3,4-dichlorophenylthio)-2-(2-methoxycarbonylethyl)propionic acid as an oil.
