실험 절차
m-Nitrobenzyl chloride (4.21 g, 24.5 mmol) was dissolved in DMF (40 mL) and added sodium methanesulfinate (3.00 g, 29.4 mmol) and the resulting mixture was stirred at room temperature for 16 hours. After evaporation of the solvent in vacuo the residue was partitioned between water (100 mL) and ethyl acetate (100 mL). The aqueous phase was extracted with ethyl acetate (100 mL) and the combined organic phases were dried (MgSO4) and evaporated in vacuo to afford 4.45 g (84%) 1-methylsulfonylmethyl-3-nitrobenzene.
