Reaction Steps

To a stirred solution of methyl 2-(methylthio)-2-phenylacetate (0.300 g, 1 equiv) in anhydrous EtOH (5 mL) was added hydrazine hydrate (0.15 mL, 2 equiv) and heated to reflux. Stirring was then continued for 18 hours. The reaction mixture was then cooled and the solvents removed under reduced pressure. The crude oil was diluted with EtOAc and washed with H2O and the organic phase dried over Na2SO4, filtered, and the solvents removed under reduced pressure to yield a yellow oil which was purified by flash chromatography on silica gel using ethyl acetate and hexanes. The purified product was a white solid (193 mg, 66%).
