실험 절차

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 (170 mg), 2,2-dimethylmalonic acid mono-t-butyl ester [CAS No. 143688-40-8] (490 mg), sodium iodide (390 mg), potassium hydrogen carbonate (182 mg), and DMA (25 mL) was stirred at 50° C. overnight. After cooling the mixture to room temperature, 1:1 mixture of water and saturated aqueous sodium chloride and ethyl acetate were added thereto, and the resulting mixture was extracted. The aqueous layer was reextracted with ethyl acetate twice. All the organic layers were combined, washed with water, and dried over anhydrous magnesium sulfate. The desiccant was filtered off, and the filtrate obtained was concentrated under reduced pressure. The residue obtained was purified by silica gel column chromatography (mixed solvent of heptane-ethyl acetate) to obtain a racemate of the captioned compound.
