117719-17-2, name is 5-Bromo-3-morpholinopyrazin-2-amine, belongs to pyrazines compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. name: 5-Bromo-3-morpholinopyrazin-2-amine
Chloroacetaldehyde (4.4 g) was mixed with isopropanol (15 mL) and a portion of the mixture (10 mL) was added to a round bottom flask containing compound 2 (1.7 g). Then the temperature was raised to 45 C and stirring was continued. After 1 h, the remaining solution was added and thetemperature raised to 65 C with continuous stirring. After TLC indicated the reaction was finished, the reaction was stopped and cooled to room temperature. Then the solution was added into a beaker containing ice water (300 mL) with continuous stirring. The brown-yellow solid that precipitated was filtered and dried to give the product in a yield of 26.8%. 1H-NMR (DMSO-d6) delta 7.93 (s, 1H),7.25 (d, J = 7.3 Hz, 1H), 7.01 (d, J = 7.3 Hz, 1H), 3.45 (s, 4H), 3.77 (d, J = 4.3 Hz, 4H).
The synthetic route of 117719-17-2 has been constantly updated, and we look forward to future research findings.
