Participants

Reaction Steps

To a 20 mL vial containing 1-[(2-bromophenyl)sulfonyl]-4-{1-[(2-bromophenyl)-sulfonyl]-1H-imidazol-4-yl}piperidine (884 mg, 1.50 mmol) were added a stirbar and DMSO (10 mL). Once the DMSO solution was homogeneous, LiOH (3 mL, 1.0 M) was added slowly. After 30 min the reaction mixture was diluted with EtOAc, washed with water (×4) and brine (×1), dried over MgSO4, filtered and concentrated to dryness to give the title compound (522 mg, 94%).
