Reaction Conditions

Reaction Steps

Ethyl 5-chlorosulfonyl-2-ethoxy-4-fluorobenzoate (1.5 g, 4.84 mmol; prepared as described in example 2) was taken up in 36 mL of anhydrous methylene chloride and cooled to 0° C. Dimethylamine (7.3 mL, 14.5 mmol) was added and the reaction mixture was stirred at 0° C. for 2 h and concentrated in vacuo. Purification of the crude residue by flash column chromatography (silica gel, eluting with 20-40% ethyl acetate in hexanes) gave ethyl 5-dimethylsulfamoyl-2-ethoxy-4-fluoro-benzoate as a white solid (1.02 g, 68%). LC-MS: 320.2 [(M+H)+].
