Reaction Steps
To a solution of 4-(6-chloro-4-(ethoxycarbonyl)chroman-7-yloxy)benzoic acid (0.050 g, 0.13 mmol), 1-(3,4-difluorophenyl)-1H-pyrazol-3-amine (0.028 g, 0.15 mmol), and 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (0.018 g, 0.13 mmol) in DMF (0.7 ml) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.028 g, 0.15 mmol), and the reaction was allowed to stir at ambient temperature for 60 hours. The reaction was diluted with EtOAc and washed with 10% citric acid, saturated sodium bicarbonate, and saturated sodium chloride. The combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated. The residue was purified by silica gel chromatography, eluting with a linear gradient of 5-70% EtOAc/hexanes to yield the desired product (0.067 g, 0.12 mmol, 91% yield).
