Adding a certain compound to certain chemical reactions, such as: 897957-06-1, name is 6-Bromo-1-methylindolin-2-one, 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 897957-06-1, HPLC of Formula: C9H8BrNO
To 1-4.2 (32.0 g, 142 mmol) in anhydrous dioxane (400 mL) is added R3 (54.4 g, 241 mmol) and potassium acetate (41.6 g, 424 mmol). The mixture is purged with Argon, [1, – Bis(diphenylphosphino)ferrocene]dichloropalladium(II) as a complex with dichloromethane (11.2 g, 14 mmol) is added and the mixture is heated to 90 C for 2 h. The reaction mixture is diluted with ethyl acetate and water, the organic layer is washed with water, dried over MgS04 and concentrated. The residue is purified via flash chromatography (cyclohexane / EA = 70:30). Yield 72%, m/z 274 [M+H]+, rt 0.67 min, LC-MS Method V011_S01.
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-Bromo-1-methylindolin-2-one, other downstream synthetic routes, hurry up and to see.
