Synthetic Route of 22353-40-8, Adding some certain compound to certain chemical reactions, such as: 22353-40-8, name is 2,3-Dichloro-5-nitropyridine,molecular formula is C5H2Cl2N2O2, 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 22353-40-8.
EXAMPLE 10 3-amino-5,6-dichloropyridine 77.2 g (0.4 mol) of 2,3-dichloro-5-nitropyridine were dissolved in 135 ml of glacial acetic acid, and 800 ml of water were added with stirring. 111.7 g (2 mol) of iron powder were introduced in portions into the mixture (temperature?50 C.). After completion of the reaction, the mixture is filtered under suction and the product extracted using ethyl acetate. The organic phase was washed with water until neutral, dried using MgSO4 and concentrated by evaporation. The product was recrystallized from toluene. Yield 85% Melting point 107 C.
