With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.144690-92-6,Triphenyl methyl olmesartan,as a common compound, the synthetic route is as follows.
The reaction flask was charged with 400 g of compound VII (0.50 mol) and 70% aqueous acetic acid solution of 3200 ml, Reaction was carried out at 50 C for 2 hours. After the completion of the reaction, the solvent was concentrated and concentrated, and ammonia was added to the residue.PH = 7, extracted with 1400 ml of ethyl acetate, the ethyl acetate layer was washed with water, and finally with anhydrous sodium sulfateDried; filtered, the filtrate was concentrated to dryness and the residue was recrystallized from ethanol to give the compound I pure product 256.1G, yield: 91.79%.
144690-92-6 Triphenyl methyl olmesartan 19036162, aDioxole compound, is more and more widely used in various.
