The invention belongs to the technical field of compound synthesis, and particularly discloses a synthesis method of 1-(2-bromophenyl)-4-(2-((2, 4-dimethylphenyl) sulfenyl) phenyl)
piperazine. The synthesis method comprises the following steps: in an
inert atmosphere, performing a
coupling reaction on votioxetine and o-bromo
iodobenzene in a
system containing a cuprous catalyst,
ethylene glycol, inorganic alkali and an
alcohol solvent to obtain 1-(2-bromophenyl)-4-(2-((2, 4-dimethylphenyl) sulfenyl) phenyl)
piperazine. According to the synthesis method provided by the invention, a cuprous substance is taken as a catalyst,
ethylene glycol is taken as a specific ligand, inorganic base is taken as an acid-binding agent, and an
alcohol solvent is taken as an
organic solvent, so that the
coupling reaction can be fully carried out on the vothioxetine and the o-bromoiodobenzene in a
reaction system, and the yield of the 1-(2-bromophenyl)-4-(2-((2, 2-dibromophenyl)-4-(2-((2, 2-dibromophenyl)-2-bromophenyl)-2-(2, 2-dibromophenyl)-2 the purity and the yield of the (2, 4-dimethylphenyl) sulfenyl) phenyl)
piperazine are improved.
