YieldReaction ConditionsOperation in experiment
12% Dissolve <strong>[23094-96-4]3-bromo-4-methoxybenzenesulfonyl chloride</strong> (2.86g, 10 mmol) in 40 ml THF at room temperature. Add 10 ml of aqueous saturated ammonium chloride solution. While stirring, chill in an ice water bath and add zinc dust (0.72g, 11 mmol) in small portions. Next add iodomethane dropwise over ten minutes and continue to stir the mixture in the ice bath for two hours. Partition the mixture between diethyl ether and water. Wash the organic layer with brine and dry over anhydrous sodium sulfate. Evaporate the solvent and recrystallize the crude solid from hexanes/diethyl ether to yield the title compound (0.34g, 12% yield).
