실험 절차
3.2 g. (8.3 mmol) 3-methyl-3-ethoxycarbonyl-5-nitro-6-(2-pyrazinoylamino)-indolin-2-one in 100 ml. ethanol are hydrogenated in 100 ml. ethanol in the presence of 0.5 g. 10% palladium on charcoal. After completion of the take up of hydrogen, the solution is filtered off from the catalyst, the ethanol is evaporated off and the residue is stirred for 1 hour in glacial acetic acid at 60° C.
