Reaction Steps

Under nitrogen atmosphere, triethylamine (0.112 mL) was added under ice-cooling to a mixture of 4-pyridinecarboxylic acid [CAS No. 55-22-1] (19.6 mg), TFFH (42.4 mg), and dichloromethane (6 mL), and the resulting mixture was stirred for 1 hour. To the resulting mixture, 3-methoxy-2,2-dimethylpropionic acid 5-({4-[amino(benzoylimino)methyl]phenylamino}-[2-fluoro-3-(2-hydroxyethoxy)-5-methoxyphenyl]methyl)-2-pyrimidin-2-yl-2H-[1,2,4]triazol-3-ylox ymethyl ester (14.9 mg) and DMAP (0.27 mg) were added, and the resulting mixture was stirred overnight at room temperature. Under reduced pressure, the solvent in the mixture was distilled off. The residue obtained was purified by reverse phase high-performance liquid chromatography (mixed solvent of acetonitrile-water, containing 0.1% of acetic acid) to obtain the captioned compound (10.4 mg).
