Adding a certain compound to certain chemical reactions, such as: 56809-84-8, 3,4-Dichloro-5-nitropyridine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 56809-84-8, blongs to pyridine-derivatives compound. Formula: C5H2Cl2N2O2
To a solution of intermediate 18-b (25 g 125.94 mmol) in ethanol (250 mL) was added cyclopropylamine (11.10 g, 194.31 mmol). The solution was warmed to 80C for 1 hour. The solvent was evaporated and water was added. The resulting mixture was extracted with dichloromethane (3×50 mL). The organic layer was washed with brine, dried with MgSC^ and concentrated. The intermediate 18-c was obtained (26 g, 94%>).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,56809-84-8, its application will become more common.
