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. 90390-33-3, name is 3-Chloro-5-fluorobenzylamine, A new synthetic method of this compound is introduced below., Computed Properties of C7H7ClFN
The compound of intermediate 2 (122 mg, 535 mumomicronIota) was provided in DMF (1.5 mL). N,N-diisopropylethylamine (280 mu, 1.6 mmol), propane phosphonic acid anhydride (T3P, 470 mu, 50% in DMF, 800 mumomicronIota) and 1-(3-chloro-5-fluorophenyl)methanamine (128 mg, 802 mumomicronIota) were added, and the mixture was stirred at room temperature for 4 days. After concentration, the remaining material was triturated with ethanol and water and the mixture was stirred for 15 minutes. The precipitate was collected by filtration, and was dried under reduced pressure. 156 mg (76% of theory) of the title compound were obtained. LC-MS (method 2): Rt = 1.12 min; MS (ESIpos): m/z = 370 [M+H]+ 1H-NMR (400 MHz, DMSO-d6) delta [ppm]: 2.323 (0.77), 2.327 (1.12), 2.332 (0.77), 2.523 (2.87), 2.665 (0.83), 2.669 (1.10), 2.674 (0.79), 2.729 (1.58), 2.889 (2.01), 4.481 (9.75), 4.496 (9.57), 7.167 (2.39), 7.174 (3.41), 7.177 (2.74), 7.191 (2.58), 7.195 (3.49), 7.198 (3.56), 7.201 (3.44), 7.205 (1.69), 7.219 (5.21), 7.224 (8.57), 7.233 (8.41), 7.242 (9.14), 7.247 (5.78), 7.260 (2.05), 7.272 (4.61), 7.277 (8.15), 7.280 (5.04), 7.313 (2.86), 7.318 (4.09), 7.324 (2.31), 7.335 (2.91), 7.341 (4.03), 7.346 (2.29), 7.457 (0.65), 7.466 (4.06), 7.470 (3.35), 7.476 (2.58), 7.483 (3.11), 7.489 (3.27), 7.500 (0.48), 7.597 (0.57), 7.607 (3.75), 7.613 (3.15), 7.620 (2.44), 7.626 (2.94), 7.630 (3.32), 7.638 (0.53), 7.823 (0.57), 8.306 (16.00), 8.986 (2.34), 9.001 (4.83), 9.015 (2.25), 9.138 (15.50), 13.287 (5.95).
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.
