2-(4-t-Butylphenyl)-3-hydroxy-4-methylcarbonylthiophene → Methyl 2-bromo-4-[(2-{1-[5-(4-t-butylphenyl)-4-hydroxy-3-thienyl]ethylidene}hydrazino)carbonyl]benzoate

Participants

Reaction Steps

Using 2-(4-t-butylphenyl)-3-hydroxy-4-methylcarbonylthiophene (55 mg, 0.20 mmol) and methyl 2-bromo-4-hydrazinocarbonylbenzoate (60 mg, 0.22 mmol) as the starting materials, the desired product was obtained in the same manner as in Synthetic Example 65 as a yellow solid (92 mg, yield 87%).
