Procedure
Using 2-(3,4-dichlorophenyl)-3-hydroxy-4-methylcarbonylthiophene (100 mg, 0.35 mmol) and methyl 2-nitro-4-hydrazinocarbonylbenzoate (93 mg, 0.39 mmol) as the starting materials, the desired product was obtained in the same manner as in Synthetic Example 65 as a yellow solid (147 mg, yield 83%).
