Introduction of a new synthetic route about C8H4BrNO2

Adding a certain compound to certain chemical reactions, such as: 6326-79-0, name is 6-Bromoisatin, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 6326-79-0, SDS of cas: 6326-79-0

General procedure: TiCl4 (0.7 mL, 6 mmol)was added to a stirred suspension of Zn powder (0.78 g, 12 mmol) in freshlydistilled anhydrous THF (15 mL) at room temperature (rt) under a dry N2atmosphere. After completion of the addition, the mixture was refluxed for 2 h.The suspension of the low-valent titanium reagent thus-formed was cooled tort. A solution of isatin or its derivatives 1 or 3 (2 mmol) in THF (10 mL) wasadded dropwise. The mixture was stirred at room temperature for about 5 minunder N2. After this period, the thin layer chromatography (TLC) analysis of themixture showed the reaction completed. The reaction mixture was quenchedwith 3% HCl (15 mL) and extracted with CHCl3 (3 50 mL). The combinedextracts were washed with water (3 50 mL) and dried over anhydrousNa2SO4. After evaporation of the solvent under reduced pressure, the crudeproduct was purified by column chromatography (petroleum ether/ethylacetate = 5:1) to give the pure products 2 or 4.

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 6-Bromoisatin, other downstream synthetic routes, hurry up and to see.
