Synthesis

7252-83-7

24241-18-7

63744-22-9

1. 3,5-dibromopyrazin-2-amine (1018 g, 4.03 mol) was dissolved in water (10 kg) at room temperature. 2. 2-bromo-1,1-dimethoxyethane (1.79 kg, 4.14 mol) was added to the above solution and mixed with stirring. 3. The reaction mixture was heated to reflux and held for 2 hours. 4. After the reaction was complete, water (15.3 kg) and sodium bicarbonate (744 g) were added to the reaction solution and stirring was continued for 15 minutes. 5. The reaction mixture was filtered and the solid product was collected. 6. 6. After drying, 6,8-dibromoimidazo[1,2-A]pyrazine (1106 g, 3.99 mmol, 99% yield) was obtained as a brown solid. 7. The structure of the product was confirmed by 1H-NMR (400 MHz, DMSO-d6): δ 7.90 (s, 1H), 8.23 (s, 1H), 9.02 (s, 1H).
