Reaction Steps

1-benzoyl-5-nitro-1H-indole (50 mg) was dissolved in a mixed solvent with methanol (2 ml) and tetrahydrofuran (2 ml), and ammonium formate of an excess amount and palladium/carbon (10%) of a catalytic amount were added. The reacted solution was stirred at around 30° C. for 30 minutes to complete the reduction, filtered through celite and then, concentrated under reduced pressure. Afterward, the residue was dissolved again in ethylacetate (10 ml), washed with water and brine, dried over anhydrous magnesium sulfate, concentrated under reduced pressure and then, triturated with isooctane and isopropyleter. As a result, the present compound (25 mg, productive yield 56%) was obtained as a solid.
