Reaction Steps

To a suspension of 4-methyl-3-oxothiopentanoic acid O-benzyl ester (0.84 g) and isopropylhydrazine hydrochloride (0.52 g) in acetonitrile (4 mL) was added triethylamine (1.4 g), and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was extracted with diethyl ether. The solvent of the organic layer was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (hexane/dichloromethane=1/1-2/3) to give the title compound (0.44 g).
