To a solution of tert-butyl 2-((pyridin-2-ylmethyl)(4-sulfamoyl-phenethyl)amino)acetate (150 mg, 0.37 mmol) in DCM (3.0 mL) and TFA (3.0 mL) was stirred at room temperature for overnight. Solvent was removed under reduced pressure to give 2-((pyridin-2-ylmethyl)(4-sulfamoylphenethyl)amino)acetic acid (129 mg, 100%). 1H NMR (400 MHz, CD3OD) 8.73 (d, J=5.6 Hz, 0.46H), 8.58 (d, J=4.4 Hz, 1H), 8.57 (t, J=8.0 Hz, 0.46H), 8.16 (t, J=7.6 Hz, 1H), 8.01 (d, J=8.4 Hz, 0.54H), 7.96 (t, J=6.8 Hz, 0.54H), 7.79 (d, J=8.4 Hz, 2H), 7.66 (d, J=7.2 Hz, 2H), 7.35 (d, J=8.4 Hz, 2H), 4.51 (s, 2H), 4.06 (s, 2H), 3.36 (t, J=7.6 Hz, 2H), 3.05 (t, J=7.6 Hz, 2H); MS (ESI), 355 (M+H)+.
