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. 54608-52-5, name is 2-Hydrazinopyrazine, A new synthetic method of this compound is introduced below., Product Details of 54608-52-5
A solution of 2-hydrazinopyrazine (1.10 g) in trifluoroacetic anhydride (10 mL) was stirred at room temperature for 4 h. To the mixture was added PPA (12 mL). The reaction mixture was heated at 80 C for another 15 h. The reaction mixture was cooled to room temperature and filtered to afford the title compound as a white solid (0.94 g, 50.00 %). The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 189.0 (M+l); ? NMR (400 MHz, CDC13) ?: 8.64 (s, 3H).
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.
