2-methylsulfinylbenzaldehyde

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 2-(methylthio)benzaldehyde (500 mg, 3.28 mmol) in 6.6 mL of dichloromethane was added m-chlorobenzoic peracid (0.85 g, 4.9 mmol) at 0° C. After being stirred at room temperature for 1 h, the reaction mixture was diluted with ethyl acetate. The solution was washed with saturated NaHCO3 aqueous solution, brine, and dried over MgSO4. After filtration, the filtrate was concentrated in vacuo, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=50/50 to 15/85) to obtain the title compound as a white crystal (493 mg, 89%). The solution was washed with saturated NaHCO3 aqueous solution, brine dried over MgSO4 After filtration the filtrate was concentrated in vacuo the residue was purified by silica gel column chromatography (hexane/ethyl acetate=50/50 to 15/85)
