To a slurry of 10% Pd/C (1.0 g) in 10 ml of ethanol was added 5-[(3-nitro-4-pyridinyl)oxy]-1H-indole (3.7 g) in 240 ml ethanol and this was shaken on a Parr apparatus for 1 hour. The mixture was filtered and the filtrate concentrated to yield an oil (3.1 g) which was eluted with ethyl acetate on a silica gel column via HPLC. The desired fractions were concentrated to an oil which solidified on standing to yield 2.6 g, m.p. 155°-157° C.
