Application of 184177-83-1, 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. 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, This 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.
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.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 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, and friends who are interested can also refer to it.
