Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 675109-26-9, name is 6-Bromoisoindolin-1-one, A new synthetic method of this compound is introduced below., Product Details of 675109-26-9
A mixture of 6-bromoisoindolin-1-one (287 mg, 1.35 mmol), 1-methyl-5-(tributylstannyl)-1H-imidazole (500 mg, 1.35 mmol), Pd(dppf)Cl2 (33 mg, 0.041 mmol) and Cs2CO3 (1.32 g, 4.05 mmol) in dioxane (50 mL) and water (8 mL) was heated to 100 C. overnight. After cooling, the mixture was concentrated under vacuum and purified by column chromatography on silica gel ((1%-3% MeOH in DCM) to afford 9A (220 mg, 76% yield) as a brown solid: 1H NMR (400 MHz, DMSO-d6) delta 8.66 (s, 1H), 7.76-7.15 (m, 4H), 7.15 (s, 1H), 4.43 (s, 2H), 3.72 (s, 3H); ESI m/z 214.1 [M+1]+.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
