| 摘要 |
The present invention relates to a method for preparing optically active 3-AMNO1-propanol derivatives as an intermediate and a method for preparing (s)-duloxetine using the same. This method can obtain optically active 3-AMNO1-propanol with higher yield and optical purity (ee) than any other conventional methods. Using this as an intermediate compound, it is possible to manufacture duloxetine which is enantiomerically pure and has high optical purity (ee). |
