Participants

Reaction Steps

To ethyl 2,4-dichloro-5-(chlorosulfonyl)benzoate (1 g, 3.15 mmol) in N,N-dimethylacetamide (10.5 mL) was added 2-fluoroaniline (1.215 mL, 12.60 mmol) dropwise over 1 minute at room temperature. The mixture was stirred at room temperature for 1 hour, and then it was diluted with ethyl acetate (35 mL). The organic solution was washed with 1 N HCl (2×13 mL) and saturated NaCl (13 mL). The organic layer was concentrated, ethanol (38 mL) was added, and the mixture concentrated to give ethyl 2,4-dichloro-5-{[(2-fluorophenyl)amino]sulfonyl}benzoate.
