Methanesulfonyl chloride → 4-tert-butyl-N-[4-chloro-2-(4-methanesulfonyl-4,5,6,7-tetrahydro-[1,2,3]triazolo[4,5-b]pyridin-1-yl)-phenyl]-benzenesulfonamide

Participants

Reaction Steps

A 4 mL scintillation vial was charged with 4-tert-butyl-N-[4-chloro-2-(4,5,6,7-tetrahydro-[1,2,3]triazolo[4,5-b]pyridin-1-yl)-phenyl]-benzenesulfonamide (synthesized according to general procedure M, 13 mg, 0.029 mmol), MeSO2Cl (5 mg, 0.04 mmol), and pyridine (500 μL). The reaction was stirred for 1 hour. The solvent was subsequently removed in vacuo and the residue purified by preparative TLC to afford 4-tert-butyl-N-[4-chloro-2-(4-methanesulfonyl-4,5,6,7-tetrahydro-[1,2,3]triazolo[4,5-b]pyridin-1-yl)-phenyl]-benzenesulfonamide: MS (ES) M+H expected 524.1, found 524.0.
