144690-92-6,is a common compound. C48H44N6O6.In an article, once mentioned the new application about 144690-92-6.
A mixture of trityl olmesartan medoxomil (4.0 g), methanol (20 mL), and water (10 mL) is stirred at 25-35C for 15 minutes. Aqueous HCI (1 mL) is added drop-wise at 25-35C. The mixture is cooled to 0-50C. Water (30 mL) is added and the mixture is further stirred at 0-5C for 1 hour. The insoluble material is removed by filtration and the pH of the filtrate is adjusted to about 3-4 by adding 10% aqueous NaHCOs at 25-35C. The mixture is extracted with dichloromethane (3chi40 ml_). The organic layers are combined and washed with water (40 ml_). The solvent is distilled under reduced pressure below 400C. Ethyl acetate (10 ml_) is added to the residue and the mixture is heated to 50-600C and stirred for 1 hour. The mixture is cooled to 25-35C. The formed solid is filtered, washed with ethyl acetate (5 ml_), and dried under vacuum at 60-700C (yield 2.0 g).
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 144690-92-6 is helpful to your research. 144690-92-6
