Synthetic Route of 178928-70-6, New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 178928-70-6, name is 2-(2-(1-Chlorocyclopropyl)-3-(2-chlorophenyl)-2-hydroxypropyl)-1H-1,2,4-triazole-3(2H)-thione, molecular formula is C14H15Cl2N3OS, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
1.1 Weigh 50 mg of the compound of formula I into a 10 mL sample vial, dissolve in 1.0 mL of diethylamine at room temperature and shake slightly until it is clear. When 5.0 mL of n-heptane was added dropwise, the solution appeared white turbid. After standing for 24 hours, light brown lump single crystals precipitated at the bottom of the bottle, and the color was darker. Filter out part of the single crystal, put it in a vacuum oven and dry for 6h, then the diethylamine solvate of the present invention can be obtained.
In the meantime we’ve collected together some recent articles in this area about 178928-70-6 to whet your appetite. Happy reading!
