Reaction Steps

A suspension of 9.7 g of (Z)-2-ethoxy-3-(1H-indol-5-yl)-acrylic acid ethyl ester in 100 ml of EtOH and 1.0 g of Pd/C (10%) was hydrogenated at 22° C. for 2 h after which time hydrogen uptake ceased. The suspension was filtered, the filtrate evaporated and the residue chromatographed on silica (n-hexane/AcOEt, 2:1) to give 8.7 g of the title compound as a white solid. MS: (M)+ 261.2.
