In an article, published in an article,once mentioned the application of 144690-92-6,molecular formula is , is a conventional compound. this article was the specific content is as follows. 144690-92-6
To 12.0g (15 mmol) of tritylolmesartan medoxomil prepared according to examples 1 or 2 69 ml of ethyl acetate was added and after that 12 ml of methanol and 2.67 ml (32 mmol) of conc. HCl were added. The mixture was stirred at room temperature for 2h and then the mixture was cooled to below 2C. To the cooled mixture 71 ml of 1% NH3 was slowly added to adjust pH to 4.93. The phases were separated and water phase was reextracted with 20 ml of ethyl acetate. Collected organic phases were dried over Na2SO4, filtered and concentrated under reduced pressure to approximately 15g of oily residue. To this residue 15 ml of ethyl acetate were added and the mixture was cooled to 20 C and stirred at this temperature for 2h, and then cooled under 0C and stirred at this temperature for 1hour. The product was filtered off and washed with 5 ml of fresh ethyl acetate and dried. Yield: 7.55 g (90%). HPLC: 99.81 % of the product, all individual impurities under 0.10%.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 144690-92-6, help many people in the next few years.C48H44N6O6
