Reaction Steps

To a suspension of 4-bromo-2-(3-methylbutyl)benzoic acid (1.3 g) and methanesulfonamide (365 mg) in N,N-dimethylformamide (12 ml) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (735 mg) and 4-dimethylaminopyridine (469 mg), and stirred at 30° C. for 16 hours. The mixture was diluted with ethyl acetate, washed with 1N aqueous hydrochloride solution, water and brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=2/1) to give 4-bromo-2-(3-methylbutyl)-N-(methylsulfonyl)benzamide (1.25 g).
