Adding a certain compound to certain chemical reactions, such as: 24241-18-7, name is 2-Amino-3,5-dibromopyrazine, belongs to Pyrazines compound, 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 24241-18-7, Recommanded Product: 2-Amino-3,5-dibromopyrazine
Example 137 Step A: Ethanol (10.0 mL) and chloroacetaldehyde (2.6953 g of 50 % by weight solution in water, 17.17 mmol) were added into a pressure tube containing 2-amino-3, 5- dibromopyrazine (2.015 gm, 7.97 mmol). The heterogeneous reaction mixture was stirred at 70C. The reaction mixture assumed a homogenous appearance after heating began, and precipitation started to appear 3 h later. After a total of 22 h of heating, the reaction mixture was cooled to rt. The precipitate was filtered, washed with EtOH (-10 mL), and exposed to high vacuum to afford impure imidazopyrazine 137A as an ash- colored solid (1.699 g). lH NMR: 9.03 (s, 1H), 8.24 (d, J = 0.9, 1H), 7.91 (d, J = 1.2, 1H). (ESI) m/z (M+H) + = 277.79.
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, 2-Amino-3,5-dibromopyrazine, other downstream synthetic routes, hurry up and to see.
