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. 56423-63-3, name is 2-Bromopyrazine, A new synthetic method of this compound is introduced below., Application In Synthesis of 2-Bromopyrazine
General procedure: A Schlenk tube was charged with the prescribed amount of catalyst, aryl halide (1.0 mmol), 3-(hydroxymethyl)phenylboronicacid (1.5 mmol), TBAB (1.0 mmol), the selected base (3.0 mmol), and water under nitrogen atmosphere. The reaction mixture was heated at 100 C for 12 h. After cooling,the mixture was extracted with CH2Cl2, the solvent was evaporated,and the product was separated by passing through a silica gel column with CH2Cl2/ethyl acetate (5:1) aseluent. The products 2f, 2j, 2l, and 2o were new compounds and were determined by 1H and C13 NMR. Other products were characterized by comparison with data in the literature.
The synthetic route of 56423-63-3 has been constantly updated, and we look forward to future research findings.
