Procedure

To a solution of N-{5-[(2-chloro-4-pyrimidinyl)acetyl]-2-fluorophenyl}-2,6-difluorobenzenesulfonamide (1.0 g, 2.3 mmol) in DMF (10 mL) was added NBS (0.49 g, 2.8 mmol). After stirring for 45 min at rt, 2-methylpropanethioamide (0.35 g, 3.4 mmol), was added and the reaction was stirred at rt. After 4 h, the reaction mixture was partitioned between ether and saturated aqueous NaHCO3. The organic layer was washed with brine, dried over anhydrous NaSCO4, filtered, and concentrated to generate 0.49 g (41% yield) as a yellow powder. MS (ESI) 525 (M+H).
