Man erhält so l-()<-Benzoyl-propyl)-4-phenylpiperidin-4-ol mit einem Schmelzpunkt von 129 bis 13011C.A mixture of 8.7 parts of γ-chlorobutyrophenone, 14.2 parts of 4-phenylpiperidin-4-ol and 0.1 part of potassium iodide in 150 parts of toluene is heated to 100 to 110 ° C. in a closed vessel The solid residue is treated with a mixture of water and ether. The ether layer is separated and added to the filtrate from the original reaction mixture. The combined toluene and ether solution is dried over anhydrous potassium carbonate, filtered and reduced to about one The concentrate is cooled, the resulting precipitate is filtered off and crystallized from diisopropyl ether. This gives l - () <- Benzoyl-propyl) -4-phenylpiperidin-4-ol with a melting point of 129 to 130 11 C.
