Participants

Reaction Steps

2-(4-t-Butylphenyl)-3-hydroxy-4-methylcarbonylthiophene (80 mg, 0.29 mmol) and methyl 5-hydrazinocarbonyl-2-thiophenecarboxylate (58 mg, 0.29 mmol) were stirred in dimethylformamide (2.9 mL) at 120° C. under heating overnight. The resulting reaction solution was concentrated, and chloroform/n-hexane was added. The precipitated solid was recovered by filtration to give the desired product as a yellow solid (79 mg, yield 60%).
