The present invention refers to a new process for the synthesis of tapentadol comprising the quantitative resolution of the racemic mixture (V) to obtain the stereoisomer of (S)-3-(dimethylamino)-2-methyl-1-(3-nitrophenyl)-propan-1-one (VII) according to the Scheme 2 below
using the (2R,3R)—O,O′-dibenzoyltartaric chiral acid wherein said resolution is quantitative.
The present invention also refers to some intermediate compounds of the new synthesis process of tapentadol.
