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. 37466-89-0, name is 3-Methoxybenzene-1,2-diamine belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Application In Synthesis of 3-Methoxybenzene-1,2-diamine
Step 1: Reaction of 1,2-diamino compound (Chemical Formula 2) with oxalic acid; A 3-methoxybenzene-l,2-diamine compound (1.86 g, 13.5 mmol) represented by Chemical Formula 2-1 and oxalic acid (1.23 g, 13.6 mmol) were added to 10 mL of 3 N HCl solution. After stirring at room temperature for 10 minutes, reaction was carried out for 3 days under reflux. Then, after cooling to room temperature, the reaction mixture was filtered. The filtered compound was repeatedly washed with cold water to obtain a quinoxaline-2,3- dione compound (2.26 g, 87%) represented by Chemical Formula 3-1.1H NMR (500 MHz, DMS(Hi6) 3.86 (s, 3H), 6.75 (d, J = 8.1 Hz1 IH), 6.80 (d, J= 8.0 Hz, IH), 7.05 (t, J = 8.2 Hz, IH), 11.24 (br s, IH), 11.91 (br s, IH);
The synthetic route of 37466-89-0 has been constantly updated, and we look forward to future research findings.
