実験手順

To a stirred and warm (40° C.) mixture of 600 parts of bromobenzene and 223 parts of aluminum chloride were added portionwise 168.8 parts of 1-acetyl-4-piperidinecarbonyl chloride. Upon completion, stirring was continued for 1 hour at 50° C. and overnight at room temperature. The reaction mixture was poured onto a mixture of 1500 parts of crushed ice and hydrogen chloride. The whole was stirred thoroughly. The precipitated product was filtered off, washed with 2,2'-oxybispropane and dissolved in a mixture of 2250 parts of trichloromethane and 200 parts of water. The layers were separated. The organic layer was dried, filtered and evaporated. The solid residue was suspended in 280 parts of 2,2'-oxybispropane. The product was filtered off and dried, yielding 94 parts (34%) of 1-acetyl-4-(4-bromobenzoyl)piperidine; mp. 120° C. (intermediate 15).
