2-[(4-aminophenyl)methylsulfonyl]ethanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A suspension of 2-{[(4-Nitrophenyl)methyl]sulfonyl}ethanol (Intermediate 148, 7.64 g, 46.3 mmol theoretical) and 10 wt % Pd/C (788 mg) in MeOH was stirred under an atmosphere of H2 at room temperature for 2 h, then filtered through a pad of celite. The filtrate was concentrated in vacuo, and the orange residue was recrystallized from MeOH/Et2O to give the desired product as light yellow crystals (3.65 g, 17.0 mmol, 37% over 3 steps). MS: M(C9H13NO3S)=215.27, (M+H)+=216.0. filtered through a pad of celite The filtrate was concentrated in vacuo the orange residue was recrystallized from MeOH/Et2O
