Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 39755-95-8, name is 5-Methoxyisatin, This compound has unique chemical properties. The synthetic route is as follows., 39755-95-8
To a suspension of 5-methoxyindoline-2,3-dione (250 mg, 1.41 mmol) in ethylene glycol (1mL) were added hydrazine monohydrate (140 mL) and KOH (79 mg, 1.41 mmol). The mixture was heated under microwave irradiation at 140 C for 5 minutes. Water was added and the mixture was neutralized with 1N HCl. The obtained suspension was extracted 3 times with ethyl acetate. The combined organic layers were dried over MgSO4, filtered and concentrated in vacuum to give 186 mg (81%) as a yellow solid and was used for the next step without further structure determination.
