Procedure

To crushed aluminum chloride (26 g) are added chlorobenzene (26 ml) and N-cinnamoyl-N-(1-benzoyl-4-piperidinyl)aniline (8.7 g) and the mixture is reacted at 110° C. for 1 hour. After cooling, the reaction mixture is poured into ice-water and the mixture is basified with aqueous sodium hydroxide solution. The mixture is extracted with dichloromethane and the solvent is concentrated. The residue is purified by silica gel column chromatography (solvent: methylene chloride) to give 1-(1-benzoyl-4-piperidinyl)carbostyril (5.9 g).
