New discoveries in chemical research and development 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 belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Formula: C30H35N5O3
To a stirred solution of (lS)-(2S)-2-(2-benzyloxy-l-ethyl-propyl)-4-{4-[4-(4-hydroxy-phenyl)- piperazin-l-yl]-phenyl}-2,4-dihydro-[l,2,4]triazole-3-one (1Og) in dimethylsulfoxide (100ml), a solution of sodium hydroxide (1.3g) in water (5ml) was added at ambient temperature and stirred for 15 minutes. To the resulting mixture (-)-(5R-cis)-5-(2,4-difluorophenyl)-5-[(lH-l,2,4- triazole-1-yl) methyl] -tetrahyro-3 -furanmethanol-4-chlorobenzene sulphonate (10.0 g) was added, raising the temperature to 35-45 C and stirred at the same temperature for 10-12 hours. To the resulting solution water was added and stirred for 60 minutes. The resulting mixture was filtered to obtain 12.5g of the title compound having purity of 97.0% by HPLC.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 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 help many people in the next few years.
