Procedure

To a stirred solution of N-(3-(thiazol-2-ylamino)phenyl)methanesulfonamide 55 (1.17 g, 1.85 mmol) in anhydrous THF (25 mL) was added N-bromosuccinimide (0.363 g, 2.03 mmol) at room temperature. Reaction mixture was stirred for 14 hours at ambient temperature. After completion of the reaction (as judged by TLC), it was concentrated and the crude product was MPLC (Biotage) silica column chromatographed using Acetone:Hexane as an eluent to obtain N-(3-((5-bromothiazol-2-yl)amino)phenyl)methanesulfonamide 56 (0.55 g, 86% yield). MS (ES) m/z 348 (M+H+).
