Reaction Steps

2-Oxopropanal methylhydrazone (10.56 mmol, 1.06 g) and (3-bromo-4-fluorophenyl)(oxo)acetaldehyde (10.56 mmol, 2.44 g) synthesized in Reference Synthetic Example 9 were dissolved in acetic acid (37 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 (160 mg, yield 5%).
