Procedure
To a solution of isophthalaldehyde (5.4 g) in CHCl3 (50 ml) and methyl 3 -mercaptopropanoate (9.2 ml) was added dropwise trimethylsilylchloride (6.5 ml). The reaction mixture was stirred 1 hour at room temperature, quenched with aqueous NH4OAc (25%), and extracted with ethylacetate. Flash chromatography of the residue using 1:1 ethylacetate hexane afforded the title compound.
