Reaction Steps
2-Oxopropanal methylhydrazone (13.7 mmol, 1.37 g) and (4-ethylphenyl)(oxo)acetaldehyde (13.5 mmol, 2.19 g) synthesized in Reference Synthetic Example 11 were dissolved in acetic acid (30 mL) and stirred at 100° C. for 0.6 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), then by silica gel thin layer chromatography (chloroform) and by silica gel thin layer chromatography (n-hexane/ethyl acetate=7/2) to give the desired product as a brown solid (255 mg, yield 8%).
