실험 절차

1-Cyano-cyclobutanecarboxylic acid ethyl ester (2.00 g, 13.0 mmol) was dissolved in ethanol (30 ml) and treated with Raney Nickel (1 ml as a slurry in water) and hydrogen gas at 4 bar and heating at 40° C. for 18 h. The reaction mixture was filtered through Dicalite and washed through with ethanol (50 ml). The solvent was removed under reduced pressure to give 1-aminomethyl-cyclobutanecarboxylic acid ethyl ester as a yellow oil (1.47 g, 72%).
