Reference of 7170-01-6, New Advances in Chemical Research in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic,A common heterocyclic compound, 7170-01-6, name is 3-Methyl-1H-1,2,4-triazole, molecular formula is C3H5N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
General procedure: TBHP (3 eq.) was added to a solution of 3-phenyl-1,2,4-triazole (0.4 mmol) 1a, benzaldehyde 2a (0.6 mmol), followed by TBAI (20 mol%) in DCE(4 mL). The reaction mixture was stirred at 120 oC under nitrogen atmosphere for 5 h. After completion of the reaction confirmed by TLC, the reaction mixture was cooled to room temperature and partitioned between water and ethyl acetate. The organic and aqueous layers were then separated and aqueous layer was extracted with ethyl acetate twice. The combined organic extracts were dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford the crude. The crude was further purified by silica gel chromatography using EtOAc/hexane as eluents to furnish the desired product 3 or 5.
