Palladium on carbon (0.055 g, 10% w/w) was added to a solution of methyl 3-methoxy-4-[1-propyl-5-[3-(propylcarbamoyl)prop-1-enyl]indol-3-ylmethyl]benzoate (0.545 g) in ethyl acetate (15 ml) and tetrahydrofuran (10 ml), and the mixture hydrogenated at atmospheric pressure for 6 hr. The catalyst was removed by filtration through diatomaceous earth, the filter cake washed with ethyl acetate, and the combined filtrate evaporated to give methyl 3-methoxy-4-[1-propyl-5-[3-(propylcarbamoyl)propyl]indol-3-ylmethyl]benzoate (0.52 g, 95%) as a white solid; mp 100°; partial NMR (300 MHz, DMSO-d6): 0.81(m, 6H, 2×CH3). 3.82(s, 3H, OCH3), 3.91(s, 3H, OCH3), 7.73(t, 1H, NH).
