Procedure

To a slurry of 10% Pd/C (1.0 g) in 10 ml of methanol was added N-(3-nitro-4-pyridinyl)-1H-indol-5-amine (4.0 g) in 230 ml methanol and this mixture was hydrogenated at 50 psi on a Parr apparatus. When the reaction was complete, the mixture was filtered through Celite and the filtrate concentrated to yield a solid (3.9 g). This material was eluted with 20% methanol/DCM on a silica gel column via HPLC. The desired fractions were concentrated to yield a solid (2.45 g) which was recrystallized from ethanol/water (10:1) to yield a solid, 1.8 g, m.p. 159°-161 ° C.
