A new process for the preparation of 4-trifluoromethylvalerophenone is described. The process described is a three step process comprising the synthesis of organomagnesium specie, coupling reaction between the of organomagnesiurn specie and trifluoromethylbenzonitrile or trifluoromethylbenzoyl chloride and preferably a purification of the product obtained in suitable reaction conditions. In the process an extraction phase of the final product is not required.
