Reaction Steps
A solution of 6.0 g (17.1 nmol) of 2-Ethyl-4-Nitro-α-oxo-1-(phenylmethyl)-1H-indole-3-acetamide in 140 ml of 1:1 THF:EtOH containing 1.0 g of 5% Pt/BaSO4 was hydrogenated at room temperature and 60 psi (4.22 Kg/cm2) for four hours. The catalyst was filtered and the filtrate evaporated in vacuo. The residue was chromatographed over silica gel eluting with Hexane/50 to 100% EtOAC to give 1.66 g (30%) of 4-Amino-2-Ethyl-α-oxo-1-(phenylmethyl)-1H-indole-3-Acetamide melting at 140-144° C.
