The present invention relates to a process for highly stereoselective synthesis of sertraline and sertraline intermediate. Thus, the mixture of 4-(3,4-Dichlorophenyl)-3,4-dihydro-N-methyl-1(2H)-naphthalenimine, 5% Pd/CaCO
3
, water and methanol is taken in a hydrogenation flask and then subjected to hydrogenation under a hydrogen pressure of 0.5 Kg at 20-35° C. for 3 hours 30 minutes. The catalyst is removed by filtration and the solvent is evaporated completely under vacuum to obtain cis-(±)-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-N-methyl-naphthalen amine. (trans-(±): 0.2).
本发明涉及一种高立体选择性合成
舍曲林和
舍曲林中间体的过程。因此,将4-(3,4-二
氯苯基)-3,4-二氢-
N-甲基-1(2H)-
萘亚胺、5% Pd/CaCO3、
水和
甲醇混合物放入氢化烧瓶中,然后在0.5千克的
氢气压力下,在20-35℃下进行3小时30分钟的氢化。通过过滤除去催化剂,然后在真空下完全蒸发溶剂,得到顺式-(±)-4-(3,4-二
氯苯基)-1,2,3,4-四氢-N-甲基-
萘胺。(反式-(±): 0.2)。
