Tert-Butylamine → N-tert-butyl-2-fluoro-4-methylbenzenesulfonamide

Participants

Reaction Conditions

Reaction Steps

To an ice cooled solution of tert-butylamine (12.55 ml) in THF (60 ml) was added a solution of 2-fluoro-4-methylbenzene-1-sulfonyl chloride (5 g) in THF (25 ml), dropwise. After stirring for 15 min at 0° C., the reaction mixture was allowed to warm and stirred at room temperature for 2 hours. The HCl salt was removed by filtration and the filtrate was concentrated to give a yellow residue, which was triturated with Et2O and Hexanes to give 5.10 g N-tert-butyl-2-fluoro-4-methylbenzenesulfonamide as an off-white granular solid.
