Versuchsvorschrift
To a 100 mL round bottom flask was added 5-nitro-2-(pyrrolidin-1-yl)pyridin-4-amine (compound 20.1, 800 mg, 3.84 mmol, 1.0 equiv) and Pd on carbon (10 wt % Pd, 400 mg, 0.38 mmol, 0.1 equiv). The system was purged with nitrogen and charged with methanol (19 mL) followed by hydrogen. The mixture was stirred at room temperature under hydrogen for 4 hours then purged with nitrogen. The mixture was filtered though celite and washed extensively with MeOH. The solvents were removed in vacuo to obtain the title compound as a purple solid (641 mg, 94%). m/z (ES+) 179.3 (M+H)+. 1H NMR (400 MHz, DMSO-d6): δ 7.27 (s, 1H), 5.62 (s, 1H), 5.14 (br s, 2H), 3.67 (br s, 2H), 3.23-3.13 (m, 4H), 1.91-1.79 (m, 4H).
