A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.144690-92-6. An updated downstream synthesis route of 144690-92-6 as follows., 144690-92-6
Into a 1000 mL four-necked flask equipped with a two-piece stirring blade having a diameter of 10 cm,50 g of trityl olmesartan medoxomil, 225 ml of acetic acid and 75 ml of water were added and stirred at 40 C. for 2 hours to carry out deprotection reaction.Subsequently, the reaction solution was cooled to 20 C. and stirred at 20 C. for 1 hour, and the precipitated triphenylmethanol was removed by vacuum filtration,To the obtained filtrate were added 250 ml of 10% sodium hydrogen carbonate and 500 ml of ethyl acetate, followed by vigorous stirring, and the aqueous layer was separated to obtain an organic layer containing olmesartan medoxomil.200 ml of ethyl acetate was distilled off from the organic layer, and the mixture was stirred at 20 to 30 C. for 1 hour. The precipitated solid was collected by filtration under reduced pressure as a wet body.The obtained wet body was dried at 40 C. for 14 hours to obtain 30 g of crystals of olmesartan medexomil (purity: 99.54%)., 144690-92-6
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps.
