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. 1001401-62-2, name is 2-(2H-1,2,3-Triazol-2-yl)benzoic acid, A new synthetic method of this compound is introduced below., name: 2-(2H-1,2,3-Triazol-2-yl)benzoic acid
Step C: (¡À)-trans-(2-(2H-1,2,3-triazol-2-yl)phenyl)(3-((5-bromopyridin-2-yl)amino)-2-methylpiperidin-1-yl)methanone. The title compound from Step B (50 mg), DIPEA (1 mL), intermediate A-4 (100 mg) and HATU (200 mg) were stirred in THF at rt for 3 h. Upon completion of the reaction, purification was performed using preparative HPLC to give the title compound (20 mg, 55% yield). MS (ESI) mass calcd. for C20H21BrN6O, 440.2; m/z found 441.1 [M+H]+. 1H NMR (CDCl3): 8.11-7.26 (m, 8H), 7.11-5.91 (m, 1H), 5.19-4.55 (m, 1H), 4.26-2.68 (m, 3H), 2.11-0.71 (m, 7H).
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.
