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
10L reaction flask was charged 500.0g (0.62mol) compound 6,3L water, 1L of acetone, was added dropwise a solution of 645.0g of 22.5% sulfuric acid at 20 . Dropping was completed, the reaction at room temperature after 4.5h TLC or HPLC in control, raw reaction was complete. Body cooling system to 0-5 , when the temperature stabilized filtrate back into the reaction vessel was charged with acetone 1L and 2L water. The system was maintained at 15 solution of 210g of potassium carbonate and 400g water to form a solution, drops of completion, stirring after 1-2h incubation filtration. The filter cake was dried to obtain olmesartan medoxomil pure 328.9g. HPLC: 99.96%, yield: 94.3%, 144690-92-6
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
