Adding a certain compound to certain chemical reactions, such as: 6905-47-1, name is 2-Amino-6-methoxypyrazine, 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 6905-47-1, Computed Properties of C5H7N3O
To a solution of 6-methoxypyrazin-2-amine (3 g, 24 mmol) in dry DMF (35 mL), N-chlorosuccinimide (3.2 g, 24 mmol) was added. The reaction mixture was stirred at room temperature for 16 h then waspoured into ice and brine (130 mL). The aqueous solution was extracted with ethyl acetate (3 x 120 mL), the organic phase was washed with 5% solution of LiCI, dried over Na2SO4 and evaporated under reduced pressure. The crude was purified by SNAP-340-NH (cyclohexane/ethyl acetate from 95:5 up to 8:2) and by SNAP1 00-Si-OH (eluting with DCM)to afford the title intermediate (1.98 g, 12.5 mmol, 52% yield). LC-MS (M-H) = 160.1
