Reference of 1257633-67-2, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 1257633-67-2 as follows.
Synthesis of 1-tert-butyl-1H-1,2,3-triazole-4-carbaldehyde To a 50-mL round bottom flask was added a solution of 1-tert-butyl-4-(diethoxymethyl)-1H-1,2,3-triazole (1.28 g, 5.63 mmol) in dichloromethane (6.0 mL), followed by addition of water (3.0 mL) and trifluoroacetic acid (1.0 mL). The reaction was stirred vigorously under nitrogen for 3 h until TLC analysis indicated the complete disappearance of the starting material (10% EtOAc in dichloromethane, starting material Rf 0.5, product Rf 0.6, KMnO4 stain). The reaction mixture was diluted with EtOAc (100 mL), washed with sat aq NaHCO3 (3*40 mL) and brine (40 mL). The combined organic phases were dried over anhydrous MgSO4, filtered, and concd in vacuo to provide 0.71 g of a light yellow oil (yield: 82%). The crude product was used without purification.
According to the analysis of related databases, 1257633-67-2, the application of this compound in the production field has become more and more popular.
