Reaction Steps

Palladium on carbon (10% w/w, 0.1 g) was added to a solution of E-4-[1-allyl-5-[2-(propylcarbamoyl)-1-propenyl]indol-3-ylmethyl]-3-methoxy-N-(2-methylphenylsulfonyl)benzamide (0.24 g) in ethanol (10 ml). The mixture was vigorously stirred and hydrogenated at atmospheric pressure for 4 hr. The catalyst was removed by filtration through diatomaceous earth, the filter pad washed with ethanol, and the filtrate evaporated. The white foam obtained was precipitated from a mixture of ethanol and 1M hydrochloric acid to give the title compound (0.2 g, 82%) as a white powder; mp 104°-110° (softens at 84°).
