Reaction Steps

2-Mercapto-benzoic acid (1.5 g, 9.73 mmol) was dissolved in a solution of NaHCO3 (2.6 g, 0.031 mol) in H2O (25 mL). The 2-mercapto-benzoic acid solution was cooled to 0° C. Benzoyl chloride (1.36 g, 9.73 mmol) was then added followed by additional Na2CO3 (2.01 g, 14.60 mmol). The reaction mixture was stirred for 30 min at 0° C. and then, after allowing it to warm to room temperature, the reaction mixture was allowed to stir for an additional 45 minutes. Subsequently the reaction mixture was acidified with concentrated HCl forming a white precipitate. The precipitate was collected washed with cold water and dried in a vacuum dessicator overnight to yield the title compound in 83% yield (2.08 g, 8.08 mmol).
