A common compound: 486460-20-2, name is 3-(Trifluoromethyl)-[1,2,4]triazolo[4,3-a]pyrazine, belongs to Pyrazines compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 486460-20-2
3-(Trifluoromethyl)-l,2,4-triazolo[4,3-a] pyrazine (540 mg, 2.87 mmol, from Step A)was hydrogenated under atmospheric hydrogen with 10% Pd/C (200 mg) as a catalyst in ethanol (10 mL)at ambient temperature for 18 h. Filtration through Celite followed by concentration gave a dark coloredoil. Dichloromethane was added to the above oil and the insoluble black precipitate was filtered off.Concentration of the filtrate gave the title compound as an oil.’H NMR (500 MHz, CDC13) 5 2.21 (br, 1H), 3.29 (t, 2H, J = 5.5 Hz), 4.09 (t, 2H, J = 5.5 Hz), 4.24 (s,2H); LC-MS 193 (M+l).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 486460-20-2, other downstream synthetic routes, hurry up and to see.
