Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.144690-92-6, molecula formula is Triphenyl methyl olmesartan, below Introduce a new synthetic route., 144690-92-6
Example 8; Olmesartan medoxomil (V); Water (10 g) was added to a solution of the starting substance (III; 20 g) in acetone (50 ml), and the mixture was heated to a mild boil for 14 h. After the reaction was completed, the mixture was cooled to 0 0C, and the formed trityl alcohol was sucked off. After concentration, a crude product was obtained, which was extracted with ethyl acetate (70 ml). After evaporating the extract and crystallizing from acetone, 10.6 g (76 %) of the product with an HPLC purity of 97.0 % was obtained. Recrystallization from ethyl methyl ketone gave 10.2 g (73 %) of the product with an HPLC purity of 99.3 %; m.p. 175-177 C.
A chemical reaction often occurs in steps, although it may not always be obvious to an observer.
