New Advances in Chemical Research, April 2021. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring.4-(Chloromethyl)-5-methyl-1,3-dioxol-2-one,which mentioned a new discovery about 80841-78-7. 80841-78-7
Example 7; Preparation of Trityl Olmesartan Medoxomil4-(1-Hydroxy-1-methylethyl)-2-propyl-1-{4-[2-(trityltetrazol-5-yl)phenyl]phenyl}methylimidazole-5-carboxylic acid dehydrate (100 g) was suspended in acetone (1 L) & heated to reflux; the solution obtained was added to suspension of potassium carbonate (15 g), potassium iodide (6 g) & 4-chloromethyl-5-methyl-1,3-dioxol-2-one (35 g) in acetone (500 mL) at reflux temperature. Reaction mass was refluxed for 2-6 hrs. After competition of reaction, the reaction mass was filtered & the acetone was distilled from combined mother liquor. The residue obtained was dissolved in toluene (1 L) toluene layer was washed with brine (3¡Á250 mL). Toluene was removed under reduced pressure & residue thus obtained was recrystallized from methanol to give trityl OlmesartanMedoxomil (100 g).HPLC purity=99.5%
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity!, 80841-78-7
