Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 24241-18-7, name is 2-Amino-3,5-dibromopyrazine, A new synthetic method of this compound is introduced below., Formula: C4H3Br2N3
(a)To a 100 mL autoclave was added 2-amino-3,5-dibromopyrazine (10 g, 39.54 mmol, 1 eq) and aqueous ammonia (50 mL, commercially available).The temperature was raised to 130 C under nitrogen atmosphere to carry out the reaction overnight (10 to 12 hours); the temperature was lowered, suction filtration, and the obtained solid was vacuum dried to obtain 5.0 g of compound II.
The synthetic route of 24241-18-7 has been constantly updated, and we look forward to future research findings.
