実験手順

A solution of 2.05 g of 5-{4-[2-(indol-1-yl)-ethoxy]benzyl}-3-triphenylmethylthiazolidine-2,4-dione (prepared as described in Preparation 14) in 100 ml of dioxane was stirred in an atmosphere of hydrogen and in the presence of 3.1 g of 10% w/w palladium-on-charcoal, first at room temperature for 30 minutes, then at 60° C. for 2 hours and then at 80° C. for 3 hours. At the end of this time, the reaction mixture was filtered to remove the catalyst and the filtrate was concentrated by evaporation under reduced pressure. The concentrate was then purified by column chromatography through silica gel, using a 2:1 by volume mixture of hexane and ethyl acetate as the eluent, to give 1.06 g of the title compound, melting at 42.3-44.6° C.
