144690-92-6, A common heterocyclic compound, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.”144690-92-6
Example 7; Olmesartan medoxomil (V); Water (20 g) was added to a solution of the starting substance (III; 20 g) in acetonitrile (100 ml), and the mixture was heated to a mild boil for 14 h. After cooling, the formed trityl alcohol was sucked off, and the mixture was concentrated. After crystallization from isopropyl acetate, 10 g (71 %) of the product with an HPLC purity of 97 % was obtained. The HPLC purity of the product recrystallized from isopropanol was 99.5 %.
The chemical industry reduces the impact on the environment during synthesis, Triphenyl methyl olmesartan, , I believe this compound will play a more active role in future production and life.
