Procedure

To 4-tert-butyl-N-[4-chloro-2-((S)-4-pyrrolidin-3-yl-4H-[1,2,4]triazol-3-yl)phenyl]-benzenesulfonamide hydrochloride (0.25 g, 0.505 mmol) in THF (8 mL) was added pyridine (0.60 mL, 7.4 mmol). The resultant solution was stirred for 20 minutes at room temperature. The reaction mixture was subsequently cooled to 0° C., methanesulfonyl chloride (0.595 mL, 7.6 mmol) was added, and the mixture was stirred overnight at room temperature. The following day, the volatiles were evaporated and the resultant residue was adsorbed onto silica gel and purified by automated normal-phase chromatography (using 50→100% EtOAc in hexanes) to obtain the title compound (0.183 g) in 67.5% yield: MS (ES) M+H expected 538.0, found 538.1.
