Reaction Steps

2-Oxopropanal methylhydrazone (11.60 mmol, 1.16 g) and (4-isobutylphenyl)(oxo)acetaldehyde (11.60 mmol, 2.21 g) synthesized in Reference Synthetic Example 15 were dissolved in acetic acid (38 mL) and stirred at 100° C. for 4.5 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), then by silica gel thin layer chromatography (chloroform) and by silica gel thin layer chromatography (n-hexane/ethyl acetate=3/1) to give the desired product as a brown solid (154 mg, yield 50).
