Adding a certain compound to certain chemical reactions, such as: 675109-26-9, name is 6-Bromoisoindolin-1-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 675109-26-9, Recommanded Product: 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]+.
