13472-85-0, 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 compound 13472-85-0, name is 5-Bromo-2-methoxypyridine. This compound has unique chemical properties. The synthetic route is as follows.
Step 2. 5-Hydroxy-2-methoxypyridine To a stirred solution of 5-bromo-2-methoxypyridine (8.9 g, 47.9 mmol) in THF (175 mL) at -78 C. was added an n-butyllithium solution (2.5 M in hexane; 28.7 mL, 71.8 mmol) dropwise and the resulting mixture was allowed to stir at -78 C. for 45 min. Trimethyl borate (7.06 mL, 62.2 mmol) was added via syringe and the resulting mixture was stirred for an additional 2 h. The bright orange reaction mixture was warmed to 0 C. and was treated with a mixture of a 3 N NaOH solution (25 mL, 71.77 mmol) and a hydrogen peroxide solution (30%; approx. 50 mL). The resulting yellow and slightly turbid reaction mixture was warmed to room temp. for 30 min and then heated to the reflux temp. for 1 h. The reaction mixture was then allowed to cool to room temp. The squares layer was neutralized with a 1N HCl solution then extracted with Et2O (2*100 mL). The combined organic layers were dried (Na2SO4) and concentrated under reduced pressure to give a viscous yellow oil (3.5 g, 60%).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 13472-85-0, 5-Bromo-2-methoxypyridine.
