Electric Literature of 1257633-67-2, These common heterocyclic compound, 1257633-67-2, name is 1-(tert-Butyl)-4-(diethoxymethyl)-1H-1,2,3-triazole, its 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.
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.
Statistics shows that 1-(tert-Butyl)-4-(diethoxymethyl)-1H-1,2,3-triazole is playing an increasingly important role. we look forward to future research findings about 1257633-67-2.
