Electric Literature of 37466-89-0, 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.
3-Methoxybenzene-1,2-diamine dihydrochloride (Example 54(a)) was partitioned between 10% aq. Na2CO3 and CH2Cl2. The aqueous layer was extracted with CH2Cl2 (2¡Á). The combined organic extracts were dried over Na2SO4, filtered and evaporated to yield 3-methoxybenzene-1,2-diamine. A mixture of the diamine (912 mg, 6.6 mmol) and diethyl oxalate (9.0 mL, 66 mmol, Aldrich) was heated at 185 C. for 18 h. The reaction mixture was left to reach room temperature and the solid precipitate was filtered. The filter cake was washed with EtOH and dried in vacuo to give the title compound. MS (ESI, pos. ion.) m/z: 191 (M+1).
The synthetic route of 3-Methoxybenzene-1,2-diamine has been constantly updated, and we look forward to future research findings.
