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
A mixture of 2-(2H-1,2,3-triazol-2-yl)benzoic acid (50 mg, 0.26 mmol) in thionyl chloride (2 mL) was stirred at 80C for 1 h, cooled to RT and concentrated in vacuo. The residue was dissolved in DCM (10 mL) and added to a solution of the product from step 5 (66 mg, 0.26 mmol) in DCM (1 mL) and DIPEA (0.1 ml) at 0C. The resulting mixture was stirred at RT for 12 h, poured into water and extracted with EtOAc (50 mL x 3). The combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated in vacuo. The crude product was purified by Prep-TLC (50% EtOAc in petroleum ether) to give the title compound as a white solid.
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.
