Synthetic Route of 103755-58-4,Some common heterocyclic compound, 103755-58-4, name is (1-Phenyl-1H-1,2,3-triazol-4-yl)methanol, molecular formula is C9H9N3O, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: 1-Azido-4-methylbenzenes 1 (0.3 mmol), propargyl alcohol 2 (0.36 mmol), CuI (0.03 mmol),NaAsc (0.06 mmol), and 2 mL solvent were added to a 15 mL pressure tube. The tube was thensealed, and the mixture was stirred at 80 C for 5 hours. After the reaction completed, the abovesystem was added with KMnO4 (0.75 mmol) and Na2CO3 (0.45 mmol), and stirred at 80 C for 8h until the reaction completed. Then, Ag2O (0.03 mmol) and K2S2O7 (0.6 mmol) were added tothe tube and the mixture was conducted at 100 C for 24 h until the transformation finished byTLC analysis. H2O (25 mL) was added to the mixture and the system was extracted with EtOAc (3¡Á 20 mL). The combined organic layer was washed with brine (3 ¡Á 5 mL), dried with Na2SO4, andconcentrated under reduced pressure to afford the crude product. Purification by columnchromatography on silica gel with EtOAc-PE (1:3) afforded the desired product 3.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route (1-Phenyl-1H-1,2,3-triazol-4-yl)methanol, its application will become more common.
