| | 3-Bromoimidazo[1,2-a]pyrimidine Usage And Synthesis |
| Uses | 3-Bromoimidozolo[1,2-a]pyrimidine can be used to prepare HPK1 inhibitors. | | Synthesis | Imidazo[1,2-a]pyrimidine (4 g) and sodium acetate (4.3 g) were dissolved in methanol (40 ml) in a 100 ml three-necked round-bottomed flask, followed by cooling the reaction mixture to -10°C. Bromine (5.38 g) was added slowly and dropwise with stirring. Upon completion of the reaction, 1M aqueous sodium sulfide (40 ml) was added to quench the reaction and the mixture was subsequently concentrated under reduced pressure to remove the solvent. Liquid-liquid extraction was carried out via ethyl acetate and water to separate the by-products, and finally the crude product was purified by column chromatography using dichloromethane and methanol as eluents to give 3.2 g of 3-bromoimidazo[1,2-a]pyrimidine. | | References | [1] European Journal of Medicinal Chemistry, 1991, vol. 26, # 1, p. 13 - 18
