In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 16727-47-2, name is 2,6-Bis(benzyloxy)-3-bromopyridine, the common compound, a new synthetic route is introduced below. Computed Properties of C19H16BrNO2
To a stirred solution of 2-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2- yl)benzo[d]thiazole (36-2) (1.1 g, 3.99 mmol) and 2,6-bis(benzyloxy)-3-bromopyridine 25-1 (1.9 g, 5.13 mmol) in a sealed tube, in Dioxane (20 mL ) and Water (2 mL ), was added K3PO4 (2.1 g, 9.12mmol) and the solution was degassed for 10 min. PdCl2(dppf)-DCM (0.400 g, 489 mumol) was added and again the solution was degassed for 5 min. After degassing completion, the sealed tube was closed with a teflon cap and the reaction mixture was stirred at 80c for 16 h. After reaction completion, as checked by TLC, the reaction mixture was filtered through celite. The organic layer was diluted with ethyl acetate, washed with water and brine, dried over anhydrous sodium sulphate, filtered and concentrated under reduced pressure. The crude material was purified by column chromatography eluted with 5 to 20 % ethyl acetate in hexane to provide 5- (2,6-Bis-benzyloxy-pyridin-3-yl)-2-methyl-benzothiazole (36-3) (1.0 g, 2.28 mmol, 57% yield). LC MS: ES+ 439.3.
The synthetic route of 16727-47-2 has been constantly updated, and we look forward to future research findings.
