Reference of 62135-58-4, Adding some certain compound to certain chemical reactions, such as: 62135-58-4, name is Ethyl [1,2,4]triazolo[1,5-a]pyridine-2-carboxylate,molecular formula is C9H9N3O2, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 62135-58-4.
Under argon atmosphere, ethyl[1,2,4]triazolo[1,5-a]pyridine-2-carboxylate (1 g, 5.23 mmol) was combined with THF (10 mL) at RT to give a brown suspension. Sodium borohydride (1.19 g, 31.4 mmol) was added in four portions. The mixture was heated to 65 C. for 15 min. After cooling down to RT, ethanol (10 mL) was added dropwise over a period of 15 min. The mixture was stirred at 65 C. for 4 h. The mixture was cooled down to 0-5 C. and NH4Cl (saturated aqueous solution, 20 mL) was added dropwise over a period of 10 min (foam.). Water (20 mL) was added and the yellow suspension was poured into dichloromethane (100 mL) and extracted with dichloromethane (4*75 mL). The combined organic layer was dried over MgSO4 and concentrated in vacuo to give the product as light yellow solid (720 mg, 4.76 mmol, 91%) which was used without further purification for the next step. MS: M=150.1 (M+H)+
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. 62135-58-4, Ethyl [1,2,4]triazolo[1,5-a]pyridine-2-carboxylate, other downstream synthetic routes, hurry up and to see.
