Participants

Reaction Steps

4-[3-[N-(2-Benzyloxyethyl)-N-(4-chlorophenyl)amino]propoxy]benzoic acid (3.5 g) was dissolved in a mixed solvent of ethanol (60 ml) and ethyl acetate (15 ml), and thereto were added conc. hydrochloric acid (0.7 ml) and 10 % palladium/carbon (0.35 g), and the mixture was stirred under hydrogen and atmospheric pressure at room temperature for 27 hours. The reaction mixture was diluted with water, filtered, and neutralized with lN aqueous sodium hydroxide solution, and then, the mixture was concentrated under reduced pressure. The residue was washed with water, and crystallized from about 50 % aqueous methanol and collected by filtration. The resultant was further recrystallized from a mixed solvent of ethyl acetate/n-hexane [1:10 (v/v)] to give the desired product (1.20 g). mp. 120°-122° C.
