Reaction Steps

To a solution of 3.24 gm (11.3 mMol) 5-ethoxycarbonyl-3-(1-methyl-1,2,5,6-tetrahydropyridin-4-yl)-1H-indole in 100 mL ethanol was added 0.8 gm 5% palladium an carbon and the reaction mixture hydrogenated at room temperature for 18 hours at an initial hydrogen pressure of 60 p.s.i. The reaction mixture was filtered and the filtrate concentrated under reduced pressure. The residual oil, which crystallized on standing at room temperature, was recrystallized from 30 mL acetonitrile to provide 1.79 gm (55%) of the desired compound as colorless crystals.
