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. 63286-28-2, name is 2-Chloro-3-hydrazinylpyrazine, A new synthetic method of this compound is introduced below., Application In Synthesis of 2-Chloro-3-hydrazinylpyrazine
A 500 mL round bottom flask was charged with 2-chloro-3-hydrazinylpyrazine (5.0 g, 35 mmol) and THF (100 mL). To the above solution was added dropwise a solution of trifluoroacetic anhydride (9.6 g, 45.6 mmol) in THF (125 mL). The resulting solution was stirred for 1 h at 0 C. Reaction progress was monitored by TLC (EtO Ac/petroleum ether = 1 :2). Work-up: the reaction mixture was diluted with water and then extracted with CH2CI2 (50 mL x 3). The combined organic layers were washed with brine (40 mL), dried over anhydrous Na2S04 and concentrated in vacuo, to afford 7.56 g (87%) of the product as a yellow solid.
The synthetic route of 63286-28-2 has been constantly updated, and we look forward to future research findings.
