实验步骤: In a 500-mL Parr shaker vessel, Raney nickel (750 mg) was added to MeOH (30 mL). Ethyl 1-cyanocyclopropanecarboxylate (Aldrich; 2.0 g, 14.38 mmol) was added and the resulting mixture was shaken vigorously under an H2 atmosphere (50 psi) for 24 h. The mixture was subsequently filtered through Celite, washing the Celite pad with MeOH (2×20 mL). The combined filtrates were concentrated in vacuo to provide ethyl 1-(aminomethyl)cyclopropanecarboxylate (1.5 g, 10.48 mmol, 73% yield): 1H NMR (400 MHz, CDCl3): δ 4.13 (q, 2H, J=7.2 Hz), 3.67 (s, 1H), 3.44 (s, 1H), 2.74 (br s, 2H), 1.27-1.21 (m, 5H), 0.80-0.74 (m, 2H). m/z (ESI, +ve) 144.4 (M+H)+. The mixture was subsequently filtered through Celite washing the Celite pad with MeOH (2×20 mL) The combined filtrates were concentrated in vacuo

实验步骤: To a solution of ethyl 1-cyanocyclopropanecarboxylate (1 g, 7.18 mmol) in ethanol-water-conc. ammonia solution (7 ml-350 μl-1 ml) was added raney nickel (ca. 350 μl) and the mixture was sittred for 24 hr at 50° C. The reaction mixture was filtered through Celite and the filtrate was concentrated in vacuo to obtain the title compound (690 mg, 67%). The reaction mixture was filtered through Celite the filtrate was concentrated in vacuo
