2-Oxopropanal methylhydrazone (7.29 mmol, 730 mg) and (3,5-dimethylphenyl)(oxo)acetaldehyde (7.29 mmol, 1.18 g) synthesized in Reference Synthetic Example 10 were dissolved in acetic acid (25 mL) and stirred at 100° C. for 5 hours. Then, the solvent was evaporated, and the residue was dried by means of a vacuum pump and purified by silica gel column chromatography (n-hexane/ethyl acetate=3/1) and then by silica gel thin layer chromatography (n-hexane/ethyl acetate=3/1) to give the desired product as an orange liquid (93 mg, yield 5%).
