Procedure
A mixture of N-[2-(4′-nitro-3′-propylaminomethyl-biphenyl-2-yl)-ethyl]-benzenesulfonamide (0.00031 mol) in methanol (50 mL) was hydrogenated with 10% Pd/C (0.100 g) as a catalyst in the presence of thiophene solution (0.5 mL). After uptake of H2 gas (3 equiv.), the reaction mixture was filtered over Dicalite and the filtrate was evaporated to yield the title compound as a residue. (The compound was used without further purification, immediately in the next reaction step.)
