To a stirred ice-cooled solution of 4-(dimethylamino)piperidine (1.2 mL, 9.4 mmol), triethylamine (2.6 mL, 19 mmol), and 4-dimethylaminopyridine (0.012 g, 0.094 mmol) in DCM (18 mL) was added 6-chloropyridine-3-sulfonyl chloride (2.0 g, 9.4 mmol) in one portion. The resulting mixture was stirred at 0° C. for 1.5 h. Upon workup, the mixture was directly subjected to combi-flash column chromatography (methanol/DCM) to give compound 363 (2.7 g, 94% yield) as a white solid. LCMS-ESI (POS), M/Z, M+1: Found 304.0.
