3-甲氧基-4-哌啶-1-基苯胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1-(2-Methoxy-4-nitro-phenyl)-piperidine (Stage 85.2; 4.0 g, 17 mmol) in ethanol/THF 5:1 (90 ml) is hydrogenated in the presence of Pd/C 10 % (“Engelhard 4505”; 0.4 g). Then the catalyst is filtered off and the filtrate is concentrated yielding the title compound: 1H-NMR (DMSO-d6): 6.58 (d, 1H), 6.19 (d, 1H), 6.04 (dd, 1H), 4.66 (s, H2N), 3.65 (s, H3CO), 2.70 (m, 4H), 1.56 (m, 4H), 1.43 (m, 2H). Then the catalyst is filtered off the filtrate is concentrated
