These common heterocyclic compound, 24241-18-7, name is 2-Amino-3,5-dibromopyrazine, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 24241-18-7
Morpholine (50 mL) was added to a three-necked flask containing 12.50 g of 3,5-dibromo-2-aminopyrazine and maintained at 80 CThe reaction was completed by the reaction of TLC for 1 h. The refluxed system was cooled to room temperature and added to a mixture containing ice water (300 mL)The mixture was stirred and dried to give 12.30 g of a yellow solid with metallic luster, i.e., 3-morpholine-5-Bromo-2-aminopyrazine in a yield of 96.1%.
The synthetic route of 2-Amino-3,5-dibromopyrazine has been constantly updated, and we look forward to future research findings.
