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. 54149-17-6, name is 1-Bromo-2-(2-methoxyethoxy)ethane belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Safety of 1-Bromo-2-(2-methoxyethoxy)ethane
Example 9. 6-{4-[4-(5-Chloro-1H-indole-2-sulphonyl)-piperazine-1-carbonyl]-phenyl}-2-[2-(2-methoxv-ethoxv)-ethvll-2H-pvridazin-3-one. 6- [4- ( {4- [ (5-Chloro-lH-indol-2-yl) sulphonyl] piperazin-1-yl} carbonyl) phenyl]- pyridazin-3-ol (see WO 99/57113,0. 054 gram, 0.11 mmol), 0. 016 gram of anhydrous potassium carbonate (0.11 mmol, 1.0 eq. ) and 0.02 gram of 1-bromo-2-(2-methoxy- ethoxy) ethane (0.11 mmol, 1.0 eq. ) were mixed in 1.5 mL of dry N, N-dimethylformamide. The mixture was treated with microwave at 150 C for 1 hour. Without any work-up, purification was performed on preparative HPLC, which gave 0.023 gram of 6-{4-[4-(5-chloro-1H-indole-2-sulphonyl)-piperazine-1-carbonyl]-phenyl}-2-[2-(2- methoxy-ethoxy)-ethyl]-2H-pyridazin-3-one (yield 36 %).
The synthetic route of 54149-17-6 has been constantly updated, and we look forward to future research findings.
