실험 절차

(E)-N-(3-hydroxyphenethyl)-3-(3-pyridyl)-2-propenoic acid amide (1.07 g, 4.0 mmol) obtained in Example 81 and methyl chloroacetate (0.52 g, 4.8 mmol) were dissolved in dimethylformamide (12 ml) and potassium carbonate (1.66 g, 12 mmol) was added and stirred at 60° C. for 8 hours. After allowing to cool, ethyl acetate was added to the reaction mixture and insoluble materials were filtered out. The filtrate was washed with water and dried over magnesium sulfate. After the solvent was distilled out under reduced pressure, the residue was recrystallized to yield the titled compound (0.83 g, 61%).
