Reaction Steps
Methyl α-methylthio(p-dimethylaminophenyl)acetate (105 mg) was dissolved in 10 ml of methanol, and 8.2 mg of sodium tungstate dihydrate and 0.6 ml of a 30% aqueous solution of hydrogen peroxide were added. The mixture was stirred at room temperature for 60 hours. The remaining hydrogen peroxide was decomposed with sodium thiosulfate, and 20 ml of water was added to the mixture. It was then extracted three times with 10 ml of methylene chloride. The organic layer was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. Recrystallization of the residue from methanol afforded 76 mg of methyl α-methylsulfonyl(p-dimethylaminophenyl)acetate in a yield of 63.5%.
