Reaction Steps

To a mixture of [1-amino-1-[4-({(5-chloromethoxy-1-pyrimidin-2-yl-1H-[1,2,4]triazol-3-yl)-[2-fluoro-3-(2-hydroxyethoxy)-5-methoxyphenyl]methyl}amino)phenyl]methylidene]carbamic acid 2,2-dimethylpropyl ester (Example 2b, 100 mg), potassium hydrogen carbonate (109 mg), and DMF (13.3 mL), 2-ethylbutanoic acid (88.3 mg) and sodium iodide (117 mg) were added, and the resulting mixture was stirred at 45° C. overnight and then cooled to room temperature. To the reaction mixture, ice and saturated aqueous ammonium chloride solution were added, and the resulting mixture was extracted with a mixture of THF and ethyl acetate. The organic layer was washed with saturated aqueous ammonium chloride solution and dried over anhydrous magnesium sulfate.
