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. 34967-24-3, name is 3,5-Dimethoxybenzyl amine, A new synthetic method of this compound is introduced below., name: 3,5-Dimethoxybenzyl amine
In a 20 mL scintillation vial, 4-amino-5-cyano-6-ethoxy-pyrindine-2-carboxylic acid (19 mg, 0.09 mmol) was dissolved in DMA (0.7 mL). Then TBTU (30 mg, 0.09 mmol) dissolved in DMA (0.7 mL) was added, followed by the addition of 3,5-dimethoxy]benzylamine (17 mg, 0.11 mmol, 1.2 eq.) in DMA (0.6 mL). Then TEA (9.37 mg, 0.09 mmol) dissolved in DMA (0.7 mL) was added. The mixture was shaken at room temperature for 24 hours. The crude mixture was purified using reverse phase HPLC (TFA). 1H NMR (500 MHz, DMSO-D6/D2O) delta ppm 1.32 (t, 3H) 3.81 (d, 6H) 4.17-4.74 (m, 4H) 5.84-7.19 (m, 4H) 9.04 (t, 1H). MS (ESI) positive ion 357 (M+H)+; negative ion 355(M-H)-.
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.
