Reaction Steps

One gram (2.33 m mol) of 4-[(1-(5-chloro-2-piperidinophenyl)-1-butyl)-aminocarbonylmethyl]-benzoic acid in 40 ml of absolute ethanol was hydrogenated on 0.5 gm of 10% palladium/charcoal at 50° C. and under 5 bar of hydrogen. After two hours, the catalyst was filtered off over kieselguhr, and the filtrate was concentrated by evaporation in vacuo. The evaporation residue was distributed at pH 6 between water and ethyl acetate. The organic extract was washed with water, dried, filtered, and evaporated in vacuo.
