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. 10541-69-2, name is (2,5-Dichlorophenyl)methanamine, A new synthetic method of this compound is introduced below., Quality Control of (2,5-Dichlorophenyl)methanamine
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 2,5-dichlorobenzylamine (18 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) ? ppm 1.24 (t, 3H) 4.03-4.86 (m, 4H) 5.88-7.87 (m, 4H). MS (ESI) positive ion 365 (M+H)+; negative ion 363(M?H)?.
The synthetic route of 10541-69-2 has been constantly updated, and we look forward to future research findings.
