Vorschrift

To a solution of Na2SO3 (1.42 g) and NaHCO3 (0.948 g) in H2O (17 ml) at 70° C. was added a solution of 5-bromo-2-methoxybenzene-1-sulfonyl chloride (2 g) in dioxane (17 ml) dropwise. The reaction mixture was stirred at 70° C. for 80 minutes and cooled to room temperature. The solvent was removed under vacuum to yield sodium 5-bromo-2-methoxybenzenesulfinate as white solid. The solid was placed under high vacuum overnight and used without further purification.
