Adding a certain compound to certain chemical reactions, such as: 98121-41-6, 3-Amino-5,6-dichloropyridine, 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, 98121-41-6, blongs to pyridine-derivatives compound. name: 3-Amino-5,6-dichloropyridine
EXAMPLE 11 5,6-dichloro-3-pyridinol Process (a) 8.15 g (50 mmol) of 3-amino-5,6-dichloropyridine were dissolved in 100 ml of 8N H2 SO4 and diazotized at 0 C. using 3.55 g (53 mmol) of sodium nitrite in 9 ml of water. The cold diazonium salt solution was added dropwise to 100 C. warm 60% strength sulfuric acid. After completion of the nitrogen elimination, the mixture was neutralized and extractively distilled using toluene. The dried toluene phase was concentrated by evaporation and the residue was recrystallized repeatedly from toluene. Melting point 184-185 C.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,98121-41-6, its application will become more common.
