3-METHYL-5-CHLORO-ANTHRANILIC ACID - Reference Information
| introduction | 2-amino -5-chloro -3-methylbenzoic acid has a melting point of 239 to 243 degrees, a density prediction of 1.4, and a solid powder appearance under normal temperature and pressure. it is a common intermediate in organic synthesis and pharmaceutical chemistry. |
| Use | 2-amino-5-chloro-3-methylbenzoic acid is a common organic synthesis intermediate. The main use is to use the benzene ring The chlorine atom is transformed into the molecular structure of the target. For example, the chlorine atom can be coupled by Suzuki, introducing an aromatic ring or alkyl chain; the carboxyl group on the benzene ring can be easily converted into ester group, hydroxyl group, amide, Webamide and so on. The amino group on the benzene ring can be converted into other active functional groups such as halogen atoms through diazotization reaction; through the selective control and coordination of these reactions, the synthesis of 1,2, 3,5-Tetrasubstituted benzene derivatives can be quickly prepared. |
| Synthesis method | For the synthesis of 2-amino -5-chloro -3-methylbenzoic acid, the synthesis method obtained by literature search is from 2-amino -3-Starting from methylbenzoic acid, it reacts with N-chlorosuccinimide under the condition of DMF as a solvent to obtain a chlorine product at the para-position of the amino group, the reaction has good regioselectivity, which may be due to the para-location reactivity caused by the strong electron donating ability of the amino group. It is worth noting that this route needs to be heated to achieve a satisfactory reaction effect. |
