Procedure
-
To a solution of tBuONSO (400 mg, 2.96 mmol), in THF (anhydrous, 12 mL) was added p-tolylmagnesium bromide (19% in tetrahydrofuran, ca. 1mol/L, 4.4 mL, 4.4 mmol) at -78 °C and the mixture was stirred at -78 °C for 1 hour. The suspension was warmed at room temperature and stirred for overnight. After that, methanol (1 mL) was add to the reaction mixture and the solvent was removed under reduced pressure. The residue was purified by column chromatography (ethyl acetate:hexane = 0:1 - 1:4 on silica gel) to give 4-methylbenzenesulfonamide as a white solid (407 mg, 80%).
