A mixture of [3-(4-nitro-3-propylaminomethyl-phenoxy)-phenyl]-carbamic acid benzyl ester (0.033 mol) in THF (200 mL) was hydrogenated with 10% Pt/C (2 g) as a catalyst in the presence of thiophene solution (2 mL). After uptake of H2 gas (3 equiv.), the reaction mixture was filtered through Dicalite, and the filtrate was evaporated. The residue was purified by column chromatography (eluent: 90:10 CH2Cl2:(CH3OH:NH3)). The product fractions were collected, and the solvent was evaporated to yield the title compound as an oil.
