Paragraph 0028-0033, (2020/06/20)
The invention discloses a preparation method of 1-(4-methoxy-benzyl)-2-methyl-octahydro isoquinoline. The preparation method comprises the following steps: dissolving 1, 2, 3, 4, 5, 6, 7, 8-octahydro-1-(methoxyphenyl) methyl isoquinoline in a solvent, adding a formaldehyde solution, stirring, adding a catalyst, introducing hydrogen, carrying out a catalytic hydrogenation reaction, filtering the catalyst out after the reaction is finished, desolventizing, and carrying out distillation separation to obtain 1-(4-methoxyl-benzyl)-2-methyl-1, 2, 3, 4, 5, 6, 7, 8-octahydro isoquinoline. The method provided by the invention has the characteristics of mild and safe reaction conditions, environmental protection, side reaction reduction, high yield, good purity, simple operation and the like, so that the preparation industry is green, environment-friendly, safe and efficient, and the production cost is reduced.
