Procedure
To a solution of α,α′-dichloro-o-xylene (3.5 g, 18 mmol) in DMF (20 mL) is added sodium methanesulfinate (0.612 g, 6.0 mmol) and the mixture is stirred at 65° C. for 4 h. Ice/water and EtOAc are added, the phases are separated and the organic phase is washed with water and brine, dried over Na2SO4/MgSO4, filtered and concentrated. The resulting residue is chromatographed on silica gel, eluting with a gradient of hexane/EtOAc to afford 1-chloromethyl-2-methanesulfonylmethylbenzene as a white solid: MS (M+NH4)+=236.
