Reference of 886762-39-6,Some common heterocyclic compound, 886762-39-6, name is 3,4-Dichloro-2-fluoroaniline, molecular formula is C6H4Cl2FN, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
3,4-Dichloro-2-fluoroaniline (1.8 g, 10 mmol), 2,4-dichloropyrimidine (2.25 g, 15 mmol) and hydrochloric acid (0.5 mL, 12 M) were added to 5mL of isopropyl alcohol and then put to reflux for 2h. The reaction mixture was cooled down to room temperature and then filtered to give the title intermediate (1.2 g). m/z: ESI 292.0.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3,4-Dichloro-2-fluoroaniline, its application will become more common.
