Downstream synthetic route of 2516-40-7

As the paragraph descriping shows that 2516-40-7 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2516-40-7,2-Bromobenzothiazole,as a common compound, the synthetic route is as follows.

9-Ethyl-3- (4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) -9H-carbazole (1 g, 3.1 mmol) is dissolved in the THF (20 mL). 2-bromobenzothiazole (0.663 g, 3.1 mmol), Pd (PPh3) 4 (0.179 g, 0.155 mmol), Na2CO3 (0.985 g, 9.3 mmol) and distilled water (4 mL) was added a After 15 hours the 70 degree in a nitrogen atmosphere heated at. After the reaction mixture was poured into distilled water (300 mL) Separate the organic layer with ethyl acetate, dry over MgSO4 and evaporate solvents. Column with ethyl acetate / hexane: separate the compound (3) by the (1 2) as a developing solvent to obtain the compound (2) to 65percent.

As the paragraph descriping shows that 2516-40-7 is playing an increasingly important role.
