Reaction Steps

To a solution of 417 mg (1 mMol) of N-[3-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)-1H-indol-5-yl]naphthalene-1-sulphonamide in 50 ml of methanol are added 100 mg of 5% palladium on carbon. The mixture is hydrogenated at ambient temperature at an initial hydrogen pressure of 3 atmospheres for 20 hours. The reaction mixture is filtered and the filtrate is concentrated at reduced pressure to provide a crude that is suspended in ethyl ether, yielding 272 mg (65%) of N-[3-(1-methyl-piperidin-4-yl)-1H-indol-5-yl]naphthalene-1-sulphonamide as a solid with m.p.=254–256° C.
