Adding a certain compound to certain chemical reactions, such as: 153435-63-3, 2-(Tributylstannyl)pyrimidine, 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, 153435-63-3, blongs to pyrimidines compound. SDS of cas: 153435-63-3
General procedure 8Intermediates 46-50 (1 eq) was dissolved dry DMF (20ml/mmol), then CsF (2 eq), CuI (0.2 eq), [Ph3P]4Pd (0.1 eq) and the corresponding Ar2-tributylstannane (1.5 eq; prepared according to Eur. J. Org. Chem. 2003, 171 1 -1721 ) were added. The mixture was warmed at 130 C for 10 minutes (microwave), then poured in aqueous saturated solution of NH4CI and extracted with AcOEt . The organic layers were combined, dried (Na2SO4) and concentrated under vacuum; crude product was purified by silica gel column chromatography (DCM to DCM/MeOH 9/1 ). The enantiomeric purity was calculated as enantiomeric eccess (ee%) by chiral HPLC methods.According to general procedure 8 the following compounds were prepared:
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,153435-63-3, its application will become more common.
