Stannous Chloride → 2-(Cyclopentylsulfonyl)benzenamine

Participants

Reaction Steps

A solution of 1-cyclopentanesulfonyl-2-nitrobenzene (0.66 g, 2.6 mmol) and SnCl2 (2.4 g, 10.34 mmol) in EtOH (10 ml) was heated under reflux for 2 h. The solvent was removed under reduced pressure and the resulting crude was dissolved in AcOEt (100 ml) and washed with sodium hydroxide 2N (30 ml) and brine (10 ml). The organic layer was dried (MgSO4) and the solvents removed under reduced pressure to give the title compound (0.38 g, 66%) as a white solid.
