Procedure
Methyl 4-chlorosulfonyl-2-ethoxy-benzoate (1.3 g, 4.55 mmol) was taken up in anhydrous methylene chloride (30 mL) and cooled to 0° C. Dimethylamine (9.1 mL, 18.2 mmol) was added. The reaction mixture was allowed to slowly warm to room temperature and stirred at room temperature for 16 h. The reaction mixture was washed with water, dried over magnesium sulfate and concentrated. Purification of the crude residue by flash column chromatography (silica gel, eluting with 20-50% ethyl acetate in hexanes) gave methyl 4-dimethylsulfamoyl-2-ethoxy-benzoate as a yellow solid (0.528 g, 41%). LC-MS: 288.1 [(M+H)+].
