The above prepared 4-acetylamino-2-fluorobenzenesulfonyl chloride (2 g, 7.9 mmol) was dissolved in dichloromethane and methylamine (9.9 mL of a 2M solution in THF, 19.9 mmol) was added. The reaction was stirred at room temperature for 2 hrs. The solvent was then evaporated under reduced pressure and the resulting solid was suspended in 50 mL of water. The solid was isolated by filtration and dried to yield 1.55 g (79%) of N-(3-fluoro-4-methylsulfamoylphenyl)acetamide which was used in the subsequent step without further purification.
