A 250 mL pressure vessel was charged with 4-tert-butyl-N-(4-chloro-2-[1,2,3]triazolo[4,5-b]pyridine-1-yl-phenyl)-benzenesulfonamide (synthesized according to general procedure G, 100 mg, 0.23 mmol), PtO2 (50 mg, 0.22 mmol), and MeOH (20 mL). The pressure vessel was placed under 60 p.s.i. of H2 and agitated for 8 hours. The reaction mixture was subsequently filtered through celite, concentrated in vacuo, and purified by preparative TLC to afford 4-tert-butyl-N-[4-chloro-2-(4,5,6,7-tetrahydro-[1,2,3]triazolo[4,5-b]pyridin-1-yl)-phenyl]-benzenesulfonamide: MS (ES) M+H expected 446.1, found 446.1.
