Brief introduction of 2-Bromo-6-chloropyridin-3-amine

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1050501-88-6, its application will become more common.

Synthetic Route of 1050501-88-6, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 1050501-88-6, name is 2-Bromo-6-chloropyridin-3-amine. A new synthetic method of this compound is introduced below.

A solution of 2-bromo-6-chloropyridin-3-amine (5 g, 24.1 mmol) and potassium thiocyanate (7 g, 72.3 mmol) in ethanol (50 ml_), hydrochloric acid (37 %, 100 mL) was added and the reaction mixture was stirred at 100 C for 40-45 h. The completion of the reaction was confirmed by TLC. The reaction mixture was cooled to room temperature and concentrated to provide a brown solid, which was partitioned in dichloromethane (150 mL) and aqueous 1 N NaOH (50 mL). The solid was filtered and dried to provide the crude title compound as a light yellow solid (3.5 g, 79 %). The product was taken as such for next step.MS: 186.1 (M+H)+.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1050501-88-6, its application will become more common.
