Electric Literature of 874-14-6, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 874-14-6 as follows.
General procedure: Uracil1 (1 mmol), the arylboronic acid 2 (3 mmol), Pd(OAc)2 (10molpercent) and 1,10-phenanthroline (15 molpercent) were combined in dry DMF (10 ml) under O2 atmosphereand stirred for 5 min (Note: DMF wasdried over calcium hydride). The reaction mixture was stirred at 90oC and monitored by TLC using EtOAc-petroleum ether as the mobilephase. After completion, the reaction mixture was cooled, and water (10 ml) wasadded. The resulting solution was then extracted with EtOAc (3 QUOTE &13;&10;&13;&10;12?”> &13;&10;&13;&10;12?”> 20 ml). TheEtOAc extract was washed with water (5 QUOTE &13;&10;&13;&10;12?”> &13;&10;&13;&10;12?”> 10 ml) and thenbrine (10 ml). The organic layer was dried with Na2SO4.Evaporation of EtOAc furnished the crude product, which was purified by flash chromatography onsilica gel (EtOAc-Petroleum ether).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,874-14-6, its application will become more common.
