A solution of [3-(benzenesulfonyl-benzyl-amino)-phenyl]-carbamic acid tert-butyl ester (1.09 g, 2.49 mmol) and trifluoroacetic acid (2.5 ml) in dichloromethane (22.5 ml) were stirred at room temperature for 90 minutes. The reaction mixture was diluted with water (100 ml) and extracted with dichloromethane (3×75 ml). The combined organics were dried (magnesium sulphate) and concentrated in vacuo to afford the title compound as a brown oil (0.83 g, 99%). HPLC retention time 5.9 min.
