실험 절차

1-ethyl-3-methoxy-2-pyridone-5-carbonitrile (30 mg) was dissolved in methanol (1 mL), and 25% sodium methoxide-methanol solution (6.6 mL) was added thereto. The mixture was stirred at room temperature for 17 hours, and methanesulfonic acid (11 μL) and a solution of (1S,2S)-1-(4-fluorophenyl)-1-(6-fluoro-3-pyridyl)-1,2-propanediamine (44.5 mg) in methanol (1 mL) were successively added. The mixture was stirred at room temperature for two days and concentrated in vacuo. The residue was dissolved in ethyl acetate, and the solution was washed with brine, and dried over anhydrous sodium sulfate. After removal of the sodium sulfate by filtration, the organic solvent was evaporated in vacuo to give a residue, which was purified by column chromatography on silica gel (chloroform:methanol=10:1) to give the title compound (1.8 mg) as a brown solid.
