Versuchsvorschrift

The 3-phenylpropionic acid hydrazide mixture (499 mg) obtained in Production Example 22-1 was dissolved in chloroform (30 mL), and triethylamine (0.86 mL) and ethyl chloroglyoxalate (0.4 mL) were added thereto, and stirred at room temperature for 5 hours. After the reaction, the reaction liquid was entirely concentrated, and the resulting residue was purified through silica gel column chromatography (chloroform/methanol=94/6) to obtain the entitled compound (760 mg).
