実験手順
From 2-(4-trifluoromethylphenyl)-3-hydroxy-4-methylcarbonylthiophene (57.3 mg, 0.2 mmol), methyl 4-hydrazinocarbonyl-2-nitrobenzoate (47.8 mg, 0.2 mmol) and tosylic acid monohydrate (11.4 mg, 0.06 mmol), 81.7 mg of the desired product was obtained in the same manner as in Synthetic Example 65 as a pale yellow solid (yield 81%).
