Reaction Steps

3-Methyl-5-phenylmethoxy-1-(4-pyridinylamino)-1H-indole (2.2 g) dissolved in absolute ethanol (80 ml) was hydrogenated at 344.74 Kpa (Parr shaker, 50 psi) over ten percent palladium on carbon (0.26 g) at 50° C. for two hours. The catalyst was removed by filtration and the solids were washed with methanol. Concentration and recrystallization from methanol afforded the title compound as a solid (0.5 g), m.p. 239°-241° C. (dec.).
