実験手順
To a solution of 6-Nitro-1H-indole-2-carboxylic acid methyl ester (108) 200 mg (0.91 mmole) in a mixture of methanol/ethylacetate 1:1 10% Pd/C (40 mg) was added. The flask was rinsed 3 times with hydrogen and filled with hydrogen at 30 to 35 psi. The suspension was stirred vigorously at room temperature for 30 minutes. The catalyst was filtered off, the filtrate was evaporated in vacuo to dryness. The resulted 6-amino-1H-indole-2-carboxylic acid methyl ester gave a single spot on TLC (Silica, toluene-ethylacetate 7:3, Rf:0.31) and was used for the next step without purification
