Synthetic Route of 571188-59-5, 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 571188-59-5 as follows.
General procedure: To a solution of alcohol (1.1 mmol) in a mixture of solvents EtOAc: DMSO (4 ml: 2 ml), was added T3P (2.5 mmol, 50% solution in ethyl acetate) at 0 C, and the resulting mixture was stirred at room temperature for 1-2 h under nitrogen atmosphere. The reaction was monitored by TLC, amine (1.0 mmol) and thioglycolic acid (1.0 mmol) were added once and stirred further for 1-3 h at room temperature. After completion of the reaction, the mixture was diluted with water (20 ml) and neutralized by adding 10% NaHCO3 solution. The product was extracted with ethyl acetate (10 ml 2) and the combined organic layers were washed with water followed by brine solution. The organic phase was dried over anhydrous Na2SO4. The solvent was removed under reduced pressure to afford a crude product which was purified by column chromatography using hexane: ethyl acetate mixture (8:2) as an eluent.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,571188-59-5, its application will become more common.
