The paper has been withdrawn, because I have posted it wrongly the first time on the arXiv. Then, I decided to change the title radically and added some more technical details

The purpose of this short note is to establish an explicit equivalence between two star products ⋆ and ⋆log on the symmetric algebra \mathrm S(\mathfrak g) of a finite-dimensional Lie algebra \mathfrak g over a field \mathbb K⊃\mathbb C of characteristic 0: the differential operator of infinite order with constant coefficients realizing the equivalence is related to the Grothendieck-Teichmüller group.
