Paragraph 0080-0082; 0086-0087, (2017/04/11)
The invention discloses a method for preparing 3-methyl-1-(2-(1-piperidyl) phenyl) butyl imine and the application of the 3-methyl-1-(2-(1-piperidyl) phenyl) butyl imine. The yield of the 3-methyl-1-(2-(1-piperidyl) phenyl) butyl imine is 30 to 35 percent; the purity of the 3-methyl-1-(2-(1-piperidyl) phenyl) butyl imine is 99.0 to 99.5 percent (detected by an HPLC (high performance liquid chromatography) method); the 3-methyl-1-(2-(1-piperidyl) phenyl) butyl imine can be used as a standard substance for detecting impurities during the preparation of repaglinide amine, and can also be used for preparing high-purity repaglinide amine after subjected to catalytic hydrogenation or preparing 3-methyl-1-(2-(1-piperidyl) butanone after subjected to acidolysis; and the prepared 3-methyl-1-(2-(1-piperidyl) butanone can be used as raw material for synthesizing repaglinide amine or 3-methyl-1-(2-(1-piperidyl) phenyl) butyl imine, so as to be recycled, and raw material waste is avoided. The method is applicable to the synthesis of repaglinide amine.
