Procedure

1-methyl-4-(2-nitro-4-(trifluoromethyl)phenylsulfonyl)piperazine was dissolved in EtOH (20 mL) and the solution was purged with argon. Pd/C (365 mg, 0.34 mmol, 10%) was added to the solution, which was stirred for 3 days in an atmosphere of hydrogen gas. The mixture was again purged with argon, filtered through Celite and concentrated under reduced pressure to afford 2-(4-methylpiperazin-1-ylsulfonyl)-5-(trifluoromethyl)benzenamine. MS m/z=324 [M+H]+. Calc'd for C12H16F3N3O2S: 323.
