144690-92-6,Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like C48H44N6O6,introducing its new discovery.
Example 7; Preparation of olmesartan medoxomilTo 75 % aqueous acetic acid (1000 ml) was slowly added trityl olmesartan medoxomil (110 gms)[prepared as described in example 5] at 25-30C. The contents were stirred at 600C for 1 hour. The reaction mass was chilled to 0-5C and filtered to remove tritanol. The reaction mass was concentrated under reduced pressure. The residue was quenched with water (500 ml), neutralized with a base and extracted in dichloromethane (500 ml). The clear dichloromethane extract was then concentrated under reduced pressure and stripped off with acetone. The residue thus obtained was isolated from the acetone (250 ml) to give 55 gms of the title compound. Chromatogrphic purity – > 99%
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
