Using the method described above for the synthesis of 4-(4-isopentylpiperazin-1-yl)aniline, treatment of 1-(4-nitrophenyl)-4-propylpiperazine (1.0 g, 4.01 mmol) with H2 and 10% Pd/C provided crude 4-(4-propylpiperazin-1-yl)aniline (0.99 g, 118% recovery due to incomplete removal of the solvent, >80% purity as determined by LC/MS analysis @ UV 254 nm detection,). The crude product is used in the next step without further purification. LCMS-ESI (m/z): calcd for C13H21N3, 219; [M+H]+ found, 220.
