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. 70838-55-0, name is 2-Chloropyrido[2,3-b]pyrazine, A new synthetic method of this compound is introduced below., category: Pyrazines
EXAMPLE 6 STR36 A mixture of 2-chloro-pyrazino[2,3-b]pyridine (3.35g), isopropanol (20 mL) and concentrated ammonium hydroxide (50 mL) was heated at 115 C. for 17 h in a sealed tube. The tube was cooled and the product was collected and recrystallized from ethanol to afford 2-amino-pyrazino[2,3-b]pyridine as a yellow solid.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
