In Example 1 the 9.9 g of anisole and the 15.7 g of 3-(1-benzoyl 4-piperidyl) propionic acid are substituted by 185 ml of 1,2 dichlorobenzene and 35 g of 3-(1-benzoyl 4-piperidyl) propionic acid respectively. The reaction is effected at 100° C. and without solvent. 51.1 g of crude 1-(3,4-dichlorophenyl) 3-(1-benzoyl 4-piperidyl) 1-propanone in the form of an oil which crystallizes slowly are obtained.
