Participants

Reaction Steps

The 4-(3-nitro-pyridin-4-yl)-piperazine-1-carboxylic acid tert-butyl ester (633 mg) was then diluted with MeOH/EtOAc (1:1, 10 mL) and to the resulting solution was added Pd on carbon (5% Pd). The resulting reaction mixture was stirred under a hydrogen atmosphere at room temperature for about 15 hours. The reaction mixture was filtered through a pad of celite and the filtrate was concentrated in vacuo to provide 4-(3-amino-pyridin-4-yl)-piperazine-1-carboxylic acid tert-butyl ester as a solid form. HPLC-MS RT=1.10 min, mass calculated for formula C14H22N4O2 278.17, observed LCMS m/z 279.28 (M+H).
