94.7% | With N-Bromosuccinimide; In water; acetonitrile; at 0 - 20℃; for 18h; | Synthesis Example 12-Amino-3,5-dibromo-6-chloropyrazine (4)To a solution of <strong>[33332-28-4]2-amino-6-chloropyrazine</strong> (3) (8.00 g, 61.8 mmol) in acetonitrile (80 mL) was gradually added N-bromosuccinimide (NBS) (27.5 g, 155 mmol) at 0° C.After elevating to room temperature, the mixture was stirred overnight (18 hours).To the mixture was added water and the product was extracted with diethyl ether (*3).The combined organic extract was washed successively with water (*1) and brine (*1), followed by drying over anhydrous sodium sulfate.After filtration and concentration under reduced pressure, the residue was purified by silica gel flash column chromatography (n-hexane/ethyl acetate=3/1) to give 2-amino-3,5-dibromo-6-chloropyrazine (4) (16.8 g, 58.5 mmol, 94.7percent) as a yellow solid. TLC Rf=0.31 (n-hexane/ethyl acetate=4/1); 1H NMR (500 MHz, CDCl3) delta 5.14 (s, 2H); 13C NMR (126 MHz, CDCl3) delta 120.7, 122.0, 146.1, 151.0. |
94.7% | With N-Bromosuccinimide; In acetonitrile; at 0 - 20℃; for 18h; | N-bromosuccinimide(NBS) (27.5 g, 155 mmol) was slowly added, was warmed up to room temperatureovernight (18 hours) and the mixture was stirred. Water was added thereto andthe product was extracted with ethyl acetate (× 3). The organic layer waswashed with water (× 1) and saturated brine (× 1), and dried over anhydroussodium sulfate. After filtration, the filtrate was concentrated under reducedpressure, and the residue was purified by silica gel flash columnchromatography (n- hexane / ethyl acetate = 3/1),2-amino-3,5-dibromo-6-chloropyrazine (4) (16.8 g , 58.5 mmol, 94.7percent) as ayellow solid |
82% | With N-Bromosuccinimide; In methanol; at 20℃; for 0.5h;Inert atmosphere; | <strong>[33332-28-4]2-Amino-6-chloropyrazin</strong>e (0.6 g, 4.63 mmol) was dissolved in MeOH (50 mL), and N-bromosuccinimide (1.81 g, 10.19 mmol) was added to the solution with stirring. The mixture was stirred at room temperature for 30 min. The reaction mixture was concentrated, ethyl acetate was added and washed with water. The organic layer was dried over MgSO4, filtered and concentrated. The residue was purified by column chromatography to give 2-amino-3,5-dibromo-6-chloropyrazine 1c (1.09 g, 82percent) as a slightly yellow solid. 1H NMR (400 MHz, CDCl3) delta5.26 (br, 2H). |
70% | With N-Bromosuccinimide; In acetonitrile; at 0 - 20℃; | To a solution of <strong>[33332-28-4]2-amino-6-chloropyrazine</strong> (1 g, 7.72 mmol) in anhydrous acetonitrile (10 mL) was gradually added NBS (4.12 g, 23.16 mmol, 3 equiv.) at 0°C. The reaction mixture was slowly warmed up to r.t. and stirred overnight then diluted with water and extracted with Et20. Combined organic layers were washed with water and brine, then dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The crude material was purified byflash chromatography on silica eluting with Hexane/EtOAc (1:1)to give the title compound (1.55 g, 5.39 mmol, 70percent) as a pale yellow solid. ESI-MS: 287.90 [M+H]+. |
38% | With N-Bromosuccinimide; In chloroform; at 20℃; for 5h;Inert atmosphere; | To a solution of 6-chloro-pyrazin-2-ylamine (5.0 g, 38.8 mmol) in chloroform (194 mL) was added N-bromosuccinimide (20.7 g, 116 mmol) under a nitrogen atmosphere and the reaction mixture was stirred at room temperature for 5 h. The resulting mixture was poured into an aqueous solution of K2CO3 (300 mL) and extracted with dichloromethane (200 mL x 4). The combined organic extracts were dried and purified by chromatography (silica, 10-20 percent ethyl acetate in hexanes) to give 3,5-dibromo-6-chloro-pyrazin-2-ylamine (4.2 g, 38percent) as a yellow solid.

The resulting mixture was purified bychromatography on silica eluting with DCM. The relevant fractions were concentrated in vacuo and the crude product was dissolved in EtOAc (~100 ml), washed with 10 percent sodium thiosulfate (2 x 100 ml), brine, dried (MgS04) and were concentrated in vacuo to afford the title compound; 1 H NMR (400 MHz, CDCI3) delta 5.4-5.0 (2H, br s). | |
With N-Bromosuccinimide; In methanol; at 15 - 20℃; for 2h;Cooling with ice; | 6-Chloropyrazin-2-amine (100 g, 772 mmol) in MeOH (2000 ml) cooled using a water bath was treated with N-bromosuccinimide (151.2 g, 170 mmol) portionwise over 30 mins, maintaining the reaction temperature between 15-20° C. After stirring for 1.5 hours, the mixture was poured carefully into a stirred vessel of ice-cooled water (4 litres). The resultant suspension was stirred for 2 hours in the ice bath, collected by filtration, rinsing the filter cake with water (800 ml) and dried in a vacuum oven to afford the titled compound; LC-MS Rt 0.99 mins; Method 2 minLowpH | |

The reaction mixture was cooledand concentrated onto silica gel (20g) and the residue loaded onto a column of silica gel(5cm x 2cm) and the column was eluted with dichloromethane. Concentration afforded3,5-dibromo-<strong>[33332-28-4]6-chloro-2-aminopyrazine</strong> that was dissolved into methanol (200 mL) andsodium methoxide (32g of a 25percent solution in methanol) added. The reaction was heated to70°C for 1.5h, cooled and concentrated to approx. 50 mL capacity.
