An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.Triphenyl methyl olmesartan, cas is 144690-92-6. Here is a downstream synthesis route of the compound 144690-92-6, 144690-92-6
Example 8; To a solution of (5-Methyl-2-oxo-1,3-dioxolen-4-yl)methyl-4-(1-hydroxy-1-methyl ethyl)-2-propyl-1-{4-[2-(trityltetrazol-5-yl)phenyl]phenyl}methylimidazole-5-carboxylate (5.0 g; 6.25 mmol) and toluene (20 ml) at 15-20 C. is added hydrochloric acid (30 ml). Reaction mass is stirred at 15-20 C. for about 15 minutes to 4 hours. The reaction is monitored by TLC. After completion of reaction layers are separated. Aqueous layer is washed with toluene (10 ml). Adjusted the pH of the aqueous layer to 5-6 using aqueous potassium carbonate solution (200 ml) and the compound is extracted using ethyl acetate (60 ml). Combined ethyl acetate layers are washed with brine. Finally crude product (3.1 g; 89.8%) is isolated by evaporation of solvent under reduced pressure.Purity: 99.5%
A chemical reaction often occurs in steps, although it may not always be obvious to an observer.
