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. 21857-45-4, name is 5-Methoxyindoline belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. Formula: C9H11NO
12 g of compound obtained in the preceding step are heated at 140 C. for 3 h in HBr (48%, 200 ml). After cooling to AT, filtering, the filtrate is concentrated dry. The residue is washed with acetone and dried. 14.8 g of desired product are obtained and used as such.
The synthetic route of 21857-45-4 has been constantly updated, and we look forward to future research findings.
