Abstract
The invention provides an improved process for preparing duloxetine. The invention provides an improved process for preparing duloxetine, efficiently and with good reaction rate, which is carried out in a homogeneous mixture, at a temperature lower than 80 °C, in which chiral integrity is preserved, and neither sodium hydride nor potassium hydroxide is required.
