Reaction Steps

To a solution of 11.3 gm (50 mMol) 5-amino-3-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)-1H-indole in 250 mL methanol were added 3.0 gm 5% palladium on carbon. The mixture was hydrogenated at room temperature under an initial hydrogen pressure of 60 p.s.i. for 18 hours. The reaction mixture was filtered and the filtrate concentrated under reduced pressure to give a dark gum which was slurried in hexane to give the title compound as a brown solid.
