YieldReaction ConditionsOperation in experiment
84.5% With hydrazine dihydrochloride; hydrazine hydrate; In ethylene glycol; at 130℃; for 6h; 10.4 g (0.1 mol) of dicyanpyridine powder was added to a 250 mL flask.Further weigh 15g (0.3mol) (85%) hydrazine hydrate and 10.5g (0.1mol) guanidine hydrochloride.Add 100 ml of ethylene glycol to the flask and reflux the reaction in an oil bath at 130 C for 6 h with constant stirring.After a few minutes, the reaction flask was changed from a large amount of pink precipitate to a yellow solution to give an orange-red solution.After the product was cooled to room temperature, the reaction mixture was diluted in 200 ml of distilled water.A large amount of precipitate is quickly produced in the beaker, filtered, washed,After naturally drying, it was recrystallized from ethanol to obtain 10.1 g of white needle crystals.The yield was 84.5%.
73% With hydrazine hydrate; sulfur; In ethanol; for 3h;Reflux; 2-Cyanopyridine (5 mL, 52 mmol) and hydrazine hydrate (8 mL of 50 -60 %) were taken in a round-bottomed flask in 10 mL of absolute ethanol. Sulfur powder (200 mg) was added to the solution and kept under reflux for 3 h. Initially, the solution turned brown and orange crystals start precipitating after 2 h. The crytalline product was filtered, which was air-dried and used without further purification. After that, the orange product was boiled with 2 M HCl solution for 1 h and the initially formed brown solution became colorless. The solution was then cooled and basi- fied with ammonium hydroxide solution and a white curd-like precipitate of 3,5-Di(2-pyridyl)-4-amino-1,2,4-triazole ( L ) was formed. The precipitate was recrystallized from dichloromethane in good yield and used for the next step. Both the ligands L 1 (2-(3,5- di(pyridin-2-yl)-4H-1,2,4-triazol-4-yl)isoindoline-1,3-dione) and L 2 (2,2 -(4-(1H-pyrrol-1-yl)-4H-1,2,4-triazole-3,5-diyl)dipyridine) have been prepared from this common synthon.
With hydrazine hydrate; In ethanol; at 120℃; for 72h;Autoclave; 4-amino-3,5-dipyridin-2-yl-4H-1,2,4-triazole (1) and 4-amino-3,5-diphenyl-4H-1,2,4-triazole (2) were synthesized in accordancewith the published procedure and checked with NMR spectra andelemental analysis.Synthesis of 4-amino-3-methyl-5-phenyl-4H-1,2,4-triazole (3)Benzonitrile (2.55 mL, 25 mmol), acetonitrile (2.61 mL, 50 mmol),NH2NH2 . H2O (80%, 9 mL) and anhydrous ethanol (3 mL) were mixedin a 100 mL Teflon-lined autoclave and heated for 3 days at 120 C.After cooling to room temperature the solvent was removed invacuum and the residue was washed with benzene (33mL). Theinsoluble part in benzene was recrystallized from 1-propanol toafford a mixture of three products. Pure samples were obtained bythe separation method using flash Silica Gel chromatography with1-propanol as eluent. Three fractions were collected. First it was 4-amino-3,5-dimethyl-4H-1,2,4-triazole (0.1654 g). The 4-amino-3-methyl-5-phenyl-4H-1,2,4-triazole (1.6782 g) (3) was eluted nextand the 4-amino-3,5-diphenyl-4H-1,2,4-triazole (0.5200 g) (2) wascollected as a third fraction.

YieldReaction ConditionsOperation in experiment
84% With acetic acid; In 1,4-dioxane; for 24h;Reflux; 3, 5-di (pyridin-2-yl)-4H-1, 2, 4-triazol-4-amine (500 mg, 2.1 mmol) was taken in a round-bottom flask and dis- solved in 1, 4-dioxane-acetic acid (1:1) mixture. Next, 2, 5- dimethoxytetrahydrofuran (330 mg, 2.5 mmol) was added and the solution was refluxed for 24 h. After work up the final product L 2 was purified by column chromatography over neutral alumina by 1% ethanol-chloroform eluent. Yield: 484 mg (84%). 1 H NMR (400 MHz, CDCl 3 ): δ(ppm) = 8.42 (2H, d, J = 2.4 Hz, H1 and H1 ), 7.73 (2H, d, J = 3.9 Hz, H4 and H4 ), 7.65 (2H, dt, J = 7.8, 1.0 Hz, H3 and H3 ), 7.20 (2H, dt, J = 4.1, 2.5 Hz, H2 and H2 ), 6.78 (2H, t, J = 1.1 Hz, H5 and H5 ), 6.13 (2H, t, J = 1.1 Hz, H6 and H6 ). FT- IR (KBr, cm -1 ): 1587 (s) ν(C = C), 1466 (m) ν(C = N) (m, medium; s, strong). UV-vis (MeOH) λ(nm) [ ε(M -1 cm -1 )]: 247 [39882], 279 [49890].
