Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 33332-28-4, name is 2-Amino-6-chloropyrazine, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 33332-28-4
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. LC-MS: 286.0 (M-H).
