Application of 14248-01-2 ,Some common heterocyclic compound, 14248-01-2, molecular formula is C5H5BrN2O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
To a solution of 5-bromo-1-methylpyrimidin-2(1H)-one (S2, 1 equiv) in DMF/H2O (9:1, 10 vol) was added compound S1 (1 equiv), K2CO3(2 equiv), and tetrakis(triphenylphosphine)palladium (0.1 equiv). The reaction mixture was stirred at 90 C. for 5 h and then concentrated under reduced pressure. The remaining residue was purified by column chromatography on silica gel to give compound S3.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,14248-01-2, its application will become more common.
