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., Safety of 2-(2H-1,2,3-Triazol-2-yl)benzoic acid
A solution of 2-(2H-1,2,3-triazol-2-yl)benzoic acid (227 mg, 1.2 mmol) in 2 mL ofSOC12 was heated at 50 C for 30 mins. After cooling to RT, the mixture was concentrated invacuo. A solution of the product from step 4 (80.0 mg, 0.41 mmol) and TEA (121 mg, 1.2 mmol) in DCM (3 mL) at 0 C was stirred for 10 mm and a solution of the above residue inDCM (1 mL) was added dropwise at 0 C. The mixture was stirred for 40 mins at 0 C. The mixture was concentrated in vacuo. The residue was purified by silica gel columnchromatography (20% EtOAc in petroleum ether) to give the title compound as a solid. LRMS m/z (M+H) 331.2 found, 331.2 required.
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.
