Versuchsvorschrift

Dimethylformamide (1.3 mL) and conc. hydrochloric acid (1 drop) were added to 2-(4-t-butylphenyl)-3-hydroxy-4-methylcarbonylthiophene (71 mg, 0.26 mmol) synthesized in Reference Synthetic Example 33 and methyl 4-hydrazinocarbonothioylamino-2-nitrobenzoate (70 mg, 0.26 mmol) synthesized in Reference Synthetic Example 56, and the mixture was stirred at room temperature for 2 days. The precipitated solid was filtered to obtain 110 mg of the desired product as a pale yellow solid (yield 81%).
