Procedure

4-Tert-butyl-2,6-dimethyl-benzenesulfonyl chloride (0.100 g, 0.383 mmol) was added to a solution of 2-methyl-3,5-bis(trifluoromethyl)aniline (0.094 g, 0.387 mmol) in dry pyridine (1 mL). The reaction was capped and stirred at room temperature for 1 day then stirred at 30° C. for 1 day. The reaction was then concentrated under vacuum. To this was added diethyl ether (60 mL) and the mixture was washed with 0.1 N HCl (3×20 mL) followed by 0.1 N NaOH (2×20 mL) then saturated NaCl (2×20 mL). After drying the organic layer over MgSO4, the solution was filtered and concentrated under vacuum. The crude compound was triturated with hexanes (3×10 mL) to afford the title compound (0.051 g, 28% yield). LCMS (M+Na) 490.
