Reaction Steps

To a solution of 4-ethoxy-2-methylsulfanyl-1-nitro-benzene (1.0 g, 5.4 mmol) in absolute EtOH (25 mL) at rt was added 40 mg of Pd/C (Aldrich, 10 wt. % on active carbon), followed by slow addition of hydrazine hydrate (0.5 mL). The resulting reaction mixture was refluxed at 90° C. for 3 h. It then cooled to rt, filtered through Celite, and then concentrated in vacuo to afford 4-ethoxy-2-methylsulfanyl-phenyl amine as a pale yellow oil: MS (ESI) 184 (M+H)+.
