Application of 184177-83-1, New Advances in Chemical Research in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 184177-83-1, name is 1-((2S,3S)-2-(Benzyloxy)pentan-3-yl)-4-(4-(4-(4-hydroxyphenyl)piperazin-1-yl)phenyl)-1H-1,2,4-triazol-5(4H)-one, molecular formula is C30H35N5O3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
2-(2(S)-Benzyloxy-l-ethyl-propyl)- 4- {4-[4-(4-hydroxy-phenyl)-piperazin- 1 -yl] -phenyl} -2,4-dihydro- [ 1 ,2,4]triazol-3-one (3 Og) was taken in 5N hydrochloric acid (60 ml) in methanol (300ml), and was hydrogenated for 2-3 hours under a hydrogen pressure of 4 kg/cm2 at 50 C in the presence of palladium on carbon (10%, 3g). After completion of reaction (monitored by TLC), the catalyst was filtered off and catalyst was washed with methanol (60 ml). The combined filtrate was concentrated and the resulting mass was dissolved in ethyl acetate (600ml) and refluxed for 1 hour. The resulting mixture was cooled, filtered to obtain 26g of the title compound having purity of 98.0% by HPLC.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 1-((2S,3S)-2-(Benzyloxy)pentan-3-yl)-4-(4-(4-(4-hydroxyphenyl)piperazin-1-yl)phenyl)-1H-1,2,4-triazol-5(4H)-one is helpful to your research.
