Procedure

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, 70 mg), potassium hydrogen carbonate (74 mg), and DMF (5 mL), sodium iodide (79 mg) and 2,2-dimethylmalonic acid monoisopropyl ester [CAS No. 7695-26-3] (92 mg) were added, and the resulting mixture was stirred at 45° C. overnight. The reaction mixture was filtered, and the filtrate obtained was concentrated under reduced pressure. The residue obtained was purified by NAM silica gel column chromatography (mixed solvent of methanol-ethyl acetate) to obtain a racemate of the captioned compound.
