Abstract:The target compound was synthesized from (4R-cis)-1,1-dimethylethyl-6-[2[2-4(fluorophenyl)-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)-carbonyl]-H-pyrrollyl]ethyl]-2,2-dimethyl-1,3-dioxane-4-acetate via three steps including acid hydrolysis, alkali hydrolysis and calcium acetate neutralization. The effects of acid, reaction medium and temperature on the reaction were studied. The results showed that the optimum reaction condition are as follows: hydrochloric acid as the hydrolyzation acid, ethanol as the solvent of reaction, the reaction temperature of 55℃. Under above conditions, the total yield was 88.7%. The structure of atorvastain calium was verified by 1H NMR and ESI-MS. |
Key words:atorvastain calium; HMG-CoA reductase inhabitor; process improvement |
