Reaction Steps
To 2,6-difluoro-3-(propane-1-sulfonylamino)-benzoic acid benzyl ester (52, 2.0 g, mmol) in methanol (30 mL) was added 20% palladium hydroxide on carbon (100 mg). The reaction was stirred under hydrogen at 1 atm for 15 minutes. The reaction was filtered and the filtrate concentrated under vacuum to provide the desired compound.
