3-Hydroxy-N-methyl-3-phenyl-propylamine is one of important intermediate of preparation fluoxetine Hydrochloride. Up to now, the method for preparing N-methyl-3-phenyl-3-hydroxy-propylamine is mainly divided into three kinds; the first kind of be replace (halogen with 3-, dialkylamine, amido or ethoxycarbonyl) Propiophenone be starting raw material, earlier after reduction, the 1-phenylpropyl alcohol that 3-is replaced is converted into 3-Hydroxy-N-methyl-3-phenyl-propylamine again; Second kind and being: the different azoles alkane of 2-methyl-5-phenyl is carried out reductive ring open makes target compound; The third be: with getting the 1-phenylpropyl alcohol that 3-replaces behind epoxy styrene and the derivative reductive ring open thereof, be translated into target compound earlier.
