Reaction Steps
235 mg Sodium sulfite and 470 mg NaHCO3 were dissolved in 1.75 mL of water and heated to 75° C. 500 mg of 4-Bromo-2-methyl-benzenesulfonyl chloride were added in portions within 10 min (gas formation) and the mixture stirred for 1 h at 75° C. 387 mg of Bromoacetic acid and 150 μL of water was added in small portions and the mixture stirred at 105° C. overnight. After cooling to 25° C. the mixture was acidified to pH 1 using 4N HCl. The resulting precipitate was collected and washed with water to yield 205 mg solid.
