Application of 7752-82-1, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 7752-82-1, name is 5-Bromopyrimidin-2-amine. A new synthetic method of this compound is introduced below.
A mixture of 5-bromo-pyrimidin-2-ylamine (0.8g, 4.59mmol), 4-bromophenyl boronic acid(1g, 4.97mmol), tetrakis(triphenylphosphine)palladium(0) (3OOmg, 0.259mmol), cesium carbonate (1.15g, 3.03mmol) was stirred in MeOH/H2O (20ml, 1/1 ) at reflux temperature overnight. The reaction was cooled to room temperature and diluted with EtOAc (200ml) and water (50ml). The organic layer was separated, dried over MgSO4, filtered and solvent evaporated yielding a residue which was purified on silica gel eluting with 85% v/vEtOAc/hexanes yielding product 81 as white solid. (0.7g, 63%). ESMS (MH, 250).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,7752-82-1, 5-Bromopyrimidin-2-amine, and friends who are interested can also refer to it.
