3080-99-7. The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a downstream synthesis route of the compound 3080-99-7, name is :3,4-Dihydro-2H-benzo[b][1,4]thiazine
(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%).
The chemical industry reduces the impact on the environment during synthesis, 3080-99-7,3,4-Dihydro-2H-benzo[b][1,4]thiazine,I believe this compound will play a more active role in future production and life.
