Reaction Steps

Methyl 5-{[(2-{1-[5-(4-t-butylphenyl)-4-hydroxy-3-thienyl]ethylidene}hydrazino)carbonothioyl]amino}-2-thiophenecarboxylate (85 mg, 0.18 mmol) synthesized in Synthetic Example 98 was dissolved in isopropyl alcohol (1.8 ml), and 0.2 M sodium hydroxide aqueous solution (1.95 ml, 0.39 mmol) was added thereto, following by stirring overnight at room temperature. Then 0.2 M sodium hydroxide aqueous solution (0.96 ml, 0.19 mmol) was added thereto, following by stirring overnight at 45° C. After completion of the stirring, 1 M hydrochloric acid (0.58 ml, 0.58 mmol) was added. The precipitated solid was filtered to obtain 2.7 mg of the desired product as a pale yellow solid (yield 3%).
