To 9.1 g (0.043 mol) of 2-bromomethyl-benzooxazole in CH3CN (300 mL) were added 7.39 g (0.045 mol, 1.05 eq) of benzenesulfinic acid sodium salt and 2.27 g (8.6 mmol, 0.2 eq) of 18-crown-6. Stirring was continued overnight, solvent evaporated and a column chromatography afforded 8.1 g (70%) of 2-benzenesulfonylmethyl-benzooxazole as a white solid, MS: 274 (H+). (Y. Nagao, S. Yamada, E.
