Procedure

To a solution of toluene-4-sulfonic acid 2-[methyl-(4-nitro-phenyl)-amino]-ethyl ester TFA salt (74 mg, 0.21 mmol) in toluene (1 mL) is added triethylamine (50 μL) and N-methylpiperazine (70 μL, 0.63 mmol). The mixture is shaken in 70° C. block shaker overnight. The reaction mixture is concentrated and purified by reverse phase high performance liquid chromatography to give methyl-[2-(4-methyl-piperazin-1-yl)-ethyl]-(4-nitro-phenyl)-amine as a tri-TFA salt (98 mg, 98%).
