実験手順

2-(3,4-Dichlorophenyl)-3-hydroxy-4-formylthiophene (52 mg, 0.19 mmol) synthesized in Reference Synthetic Example 26 and 4-hydrazinocarbonothioylaminobenzoic acid (40 mg, 0.19 mmol) were stirred with dimethylformamide (1.9 mL) and concentrated hydrochloric acid (0.1 mL) at room temperature for 14 hours. Water was added to the reaction solution, and the precipitated solid was recovered by filtration and dried. The crude product was stirred with chloroform at room temperature and recovered by filtration to give the desired product as a pale yellow solid (58 mg, yield 65%).
