As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 4595-60-2, name is 2-Bromopyrimidine, molecular formula is C4H3BrN2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Application In Synthesis of 2-Bromopyrimidine
A mixture of 2-bromopyrimidine (0.43g,2.70mmol), 2-bromopyridine-5-boronic acid (0.55g,2.72mmol), tetrakis(triphenylpnosphine)palladium(0) (3OOmg, 0.259mmol), cesium carbonate (1.15g, 3.03mmol) was stirred in MeOH/toluene/water (15ml, 1/1/1) 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 MgSd, filtered and solvent evaporated yielding a residue which was purified on silica gel eluting with 25% v/vEtOAc/hexanes yielding product 76 as white solid. (0.55g, 85%) ESMS (MH, 236).
With the rapid development of chemical substances, we look forward to future research findings about 4595-60-2.
