Some common heterocyclic compound, 552330-86-6, name is 5-Bromoisoindolin-1-one, molecular formula is C8H6BrNO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Product Details of 552330-86-6
To R8 (100 mg, 0.47 mmol) in anhydrous dioxane (8 mL) is added R5 (180 mg, 0.71 mmol) and potassium acetate (140mg, 1.43 mmol). The mixture is purged with Argon, PdCl2(dppf) (40 mg, 0.049 mmol) added and heated to 80 C for 1.5 h. The reaction mixture is diluted with EA and water, the organic layer washed with brine, dried and concentrated. The crude product is carried on. m/z 260 [M+H]+, rt 0.64 min LC-MS Method b.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 552330-86-6, its application will become more common.
