3-((7-Methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-a]pyridine-6-carbonitrile (0.050 g, 0.15 mmol) was dissolved in concentrated sulfuric acid (0.5 mL). The reaction mixture was heated at 50° C. for 30 minutes. The reaction mixture was slowly poured in to cold saturated aqueous sodium bicarbonate. A precipitate formed which was collected on a glass frit, washing with water. The solid was transferred with dichloromethane/methanol to a flask and dried under high vacuum to afford 3-((7-methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-a]pyridine-6-carboxamide (0.050 g, 95% yield) as a tan solid. MS (ESI pos. ion) m/z: 350.2 (MH+).
