실험 절차

5% Pd/C (0.3 g, 50% wet) is added to a solution of 4-(2-methylallyl)piperidine-1,4-dicarboxylic acid-1-tert-butyl ester-4-ethyl ester (1.0 g, 0.0032 mol) in ethanol (10 mL). The reaction mixture is stirred under the positive pressure of hydrogen gas for 1 hr at room temperature. The reaction mixture is filtered through celite bed and washed with ethanol (15 mL). Combine filtrate is concentrated under reduced pressure to get 4-isobutylpiperidine-1,4-dicarboxylic acid-1-tert-butyl ester-4-ethyl ester.
