3080-99-7, 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. 3,4-Dihydro-2H-benzo[b][1,4]thiazine, cas is 3080-99-7,the thiazines compound, it is a common compound, a new synthetic route is introduced below.
(3d) Potassium carbonate (5.2 g, 37.7 mmol) and methyl 4-(bromomethyl)benzoate (2.8 g, 12.6 mmol) were added to a solution of (3c) (1.9 g, 12.6 mmol) in 20 mL of anhydrous DMF. The reaction mixture was heated to 80 C. overnight. After cooling to rt, the solid was filtered off and rinsed with DMF. The filtrate was concentrated in vacuo and the residue was purified on silica gel column to provide methyl 4-(2,3-dihydro-4H-1,4-benzothiazin-4-ylmethyl)benzoate (3.02 g, 80%).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 3,4-Dihydro-2H-benzo[b][1,4]thiazine, 3080-99-7
