実験手順

6.12 g of 4-{2-[2-(2-Allyloxycarbonyl-vinyl)-1-benzhydryl-5-chloro-1H-indol-3-yl]-ethoxy}-benzoic acid methyl ester (0.098M, 1 eq.) and 1.12 g of tetrakis(triphenylphosphine) palladium (0) (0.001M, 0.1 eq.) were added to 75 mL of THF. To the reaction 8.60 ml of morpholine (0.098M, 1 eq.) was added drop-wise over 20 min. After addition was complete the reaction was stirred at room temperature for 4 hours. The reaction was poured into 250 mL of ethyl acetate and the organic solution was extracted with 1N NaOH (2×75 mL). The aqueous layers were combined and acidified with 1N HCl, the acidic solution was extracted with ethyl acetate (3×75 mL). The organic layers were combined and washed with brine (1×50 mL), dried over magnesium sulfate, filtered and evaporated to yield 4-{2-[1-Benzhydryl-2-(2-carboxy-vinyl)-5-chloro-1H-indol-3-yl]-ethoxy}-benzoic acid methyl ester as a yellow oil (5.40 g, 97% yield).
