Thiophenol → 5-Chloro-2-hydroxy-N-methyl-benzenesulfonamide

Participants

Reaction Steps

To a solution of sodium hydride (60% in mineral oil, 90.24 mg, 2.25 mmol) in dry dimethyl formamide was added thiophenol (0.225 ml, 2.25 mmol) dropwise. To this was then added 5-Chloro-2-methoxy-N-methyl-benzenesulfonamide (531 mg, 2.25 mmol) followed by refluxing for 4 hours. The reaction mixture was cooled, diluted with ethyl acetate and washed with a 1N sulfuric acid solution. The organic layer was separated, dried over magnesium sulfate, filtered and concentrated in vacuo. Chromatography on silica gel yielded the above titled compound (320 mg, 53% yield).
