実験手順

To a solution of 4-(4-methyl-2-nitro-phenylamino)-piperidine-1-carboxylic acid tert-butyl ester (9.5 g, 28.4 mmol) in ethanol (150 mL) was added 10% Pd/C (125 mg) and the reaction mixture was shaken under H2 (50 psi) at rt for 1 h. The catalyst was then removed by filtration through a pad of Celite® and washed with ethanol. The filtrate was concentrated in vacuo to provide 4-(2-amino-4-methyl-phenylamino)-piperidine-1-carboxylic acid tert-butyl ester (7.83 g) in 90% yield.
