Synthetic Route of 6326-79-0, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 6326-79-0 name is 6-Bromoisatin, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

The mixture of IX-1 (6.5 g, 28.7 mmol), malonic acid (3.3 g, 31.7 mmol), NaOAc (2.95 g, 36 mmol) in AcOH (60 mL) were stirred at rt. After 6 hrs, NaOAc (2.95 g, 36 mmol) was added additional, then refluxed overnight. After cooling, the mixture was filtered and the filtrate was washed with water and EtOAc, then dried under reduced pressure to afford IX-2 (5 g, yield 66%) as a brown oil, which was used for next step directly.

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 6-Bromoisatin, and friends who are interested can also refer to it.
