2-Chloro-N-(2-hydroxyethyl)-5-nitro-benzenesulfonamide → 3-amino-N-(2-hydroxyethyl)benzenesulfonamide

Participants

Reaction Steps

2-Chloro-N-(2-hydroxyethyl)-5-nitro-benzenesulfonamide (1.00 g, 3.57 mmol) was dissolved in methanol (35 ml) and placed under an atmosphere of nitrogen prior to the addition of 10% Pd/C (10 Wt %, 100 mg) in one portion. The reaction was evacuated, placed under an atmosphere of hydrogen (1 bar) and stirred vigorously overnight. The reaction was filtered through celite and the filtrate was concentrated in vacuo to afford the named product (0.77 g, 100%); LCMS Rt=1.44 min, m/z (ES+) 217 (M+H).
