A solution of 6-methyl-1-(pyridin-2-yl)-1H-[1,2,3]triazolo[4,5-c]pyridine (530 mg, 1.932 mmol) in acetic acid (100 mL) was passed through a Rh/C cartridge using an HCube® hydrogenation apparatus at 90 bar, 90° C. and 1 mL/min. The acetic acid was concentrated and to the residue was added 1N NaOH until pH 12 was obtained. The water layer was extracted with 20% IPA/CH2Cl2 three times. The organic layers were combined, dried over anhydrous MgSO4, filtered and concentrated to a light brown solid (243 mg, 58%). MS (ESI) mass calcd.
