Adding a certain compound to certain chemical reactions, such as: 143262-17-3, name is tert-Butyl 7-bromoindoline-1-carboxylate, 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 143262-17-3, 143262-17-3
tert-butyl 7-(4,4,5,5-tetramethyl-l,3,2-dioxaborolan-2-yl)indoline-l- carboxylate (2): A solution of tert-butyl 7-bromoindoline-l -carboxylate (300 mg, 1.0 mmol) in 1,4-dioxane (6.0 rnL) was treated with bis-pinacolatodiborane (307 mg, 1.2 mmol), potassium acetate (297 mg, 3.0 mmol), and [1,1′- bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with dichloromethane (41 mg, 0.05 mmol) at 100 ¡ãC for 6 h. After completion of the reaction, the solvent was removed under reduced pressure. The resulting residue was diluted with ethyl acetate and filtered through celite. The filtrate was concentrated under reduced pressure and the residue obtained purified by silica gel column chromatography to afford 2 (260 mg, 75percent) as a pale yellow liquid. MS m/z (M+H): 346.2.
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, tert-Butyl 7-bromoindoline-1-carboxylate, other downstream synthetic routes, hurry up and to see.
