    摘要: A process for the manufacture of agomelatine and its intermediate N-[2-(7-methoxy- 1-naphthy)ethyl]phthalimide is provided and inclues reacting 7-methoxy-1-naphthyl ethanol (III) with benzenesulfonyl chloride to obtain 7-methoxy-1 -naphthylethyl benzene sulfonate (IV), which is reacted with potassium phthalimide to produce N-[2-(7-methoxy-1-naphthy)ethyl]phthalimide (II); and subjecting N-[2-(7-methoxy-1-naphthy)ethyl]phthalimide (II) to alkaline hydrolysis and acetylation, to obtain agomelatine.
