Participants

Reaction Steps

Palladium on carbon (10% w/w, 0.01 g) was added to a solution of E-4-[6-[2-(propylcarbamoyl)vinyl]indol-1-ylmethyl]-3-methoxy-N-(2-methylphenylsulfonyl)benzamide (0.1 g) and triethylamine (0.026 ml) in ethanol (5 ml). The mixture was vigorously stirred and hydrogenated at atmospheric pressure. When hydrogen uptake had ceased, the catalyst was removed by filtration through diatomaceous earth, the filter pad washed with ethanol, the filtrate diluted with water (10 ml) and acidified to pH 4 with 1M hydrochloric acid. The ethanol was evaporated; and the white solid which precipitated from the aqueous residue was isolated by filtration, washed with water and dried to give the title compound (80 mg, 80%) as a white solid; mp 110°.
