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-l-(3-nitrophenyl)-propan-l-one (VII) according to the Scheme 2 below (V, VI, VII) Scheme 2 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.
