3-((7-Methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-a]pyridine-6-carboxylic acid (0.047 g, 0.13 mmol), cyclopropanamine (0.011 ml, 0.16 mmol), 1-hydroxy-7-azabenzotriazole (0.018 g, 0.13 mmol), and N-ethyl-N′-(3-dimethylaminopropyl)carbodiimide hydrochloride, (0.039 g, 0.20 mmol) were added to a reaction flask then suspended in DMF (1 mL). N-Ethyldiisopropylamine (0.070 ml, 0.40 mmol) was added to the reaction mixture. The clear reaction mixture was stirred at 20° C. overnight. The reaction mixture was concentrated under vacuum then triturated with water. The solid was collected on a glass frit, washing with water. The sample was purified by preparative TLC eluting with 8% 7N ammonia in methanol/dichloromethane to afford N-cyclopropyl-3-((7-methoxyquinolin-4-yloxy)methyl)-[1,2,4]triazolo[4,3-a]pyridine-6-carboxamide (0.023 g, 44% yield) as a tan solid.
