Participants

Reaction Steps

To a solution of tert-butyl 3-((3,5-dichloro-2-hydroxy-N-(4-(trifluoromethyl)benzyl)phenylsulfonamido)methyl)benzylcarbamate (0.4 g, 0.65 mmol) in CH2Cl2 (10 mL) was added TFA (1.49 mL, 19.4 mmol). The resulting mixture was stirred at rt for 16 h. The mixture was concentrated, and the residue was partitioned between saturated NaHCO3 and ethyl acetate. The organic layer was washed with brine twice, dried over MgSO4, and concentrated in vacuo to give a light yellow solid (0.32 g, 86%). 1H NMR (DMF-d7): δ 7.52 (m, 2H), 7.50 (m, 4H), 7.48 (m, 2H), 7.2-7.0 (m, 2H), 4.75 (s, 2H), 4.51 (s, 2H), 4.25 (m, 2H); MS (ESI): (M+H)+=519.11.
