Adding a certain compound to certain chemical reactions, such as: 69214-33-1, name is 8-Chloroimidazo[1,2-a]pyrazine, 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 69214-33-1, Application In Synthesis of 8-Chloroimidazo[1,2-a]pyrazine
To a mixture of 8.-chIoroirnidazo[12.-a]pyrazinc (500 mg, 3.3 rnrnol) in AcOH (5 mL) was added Br2 (800 mg, 5.0 mmol) at RT. The resulting mixture was stirred at RT for 2 days, then poured into water (20 mL) and extracted with EtOAc (15 mL x 3). The combined organic layer was washed with aqueous sodium bicarbonate solution and brine, dried over MgSO,filtered and concentrated in vacuo. The residue was purified by chromatography on silica (9.?16% EtOAc in petroleum ether) to give the title compound (30() mg) as a yellow solid. LRMSm/z (M+H) 232.2, 234.1 found, 231.2, 234.1 required.
