実験手順

To a solution of (2-(4-benzyl-4-(N′,N′-dimethylhydrazinocarbonyl)piperidine-1-yl)-1-(1H-indole-3-ylmethyl)-2-oxoethyl)carbamic acid tert-butyl ester (0.40 g, 0.73 mmol) in methylene chloride (3 ml) at 0° C. was added trifluoroacetic acid (3 ml) and the mixture was stirred for 30 min. The mixture was quenched with ethanol (20 ml), concentrated in vacuo and stripped three times with methylene chloride to give 0.63 g of 1-(2-amino-3-(1H-indol-3-yl)propionyl)-4-benzylpiperidine-4-carboxylic acid N′,N′-dimethylhydrazide as a colorless oil.
