Procedure
To a solution tert-butyl 2-(((1-methyl-1H-imidazol-2-yl)methyl)(4-sulfamoylphenethyl)amino)acetate (110 mg, 0.27 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-(((1-methyl-1H-imidazol-2-yl)methyl)(4-sulfamoylphenethyl)amino)acetic acid. A solution of 2-(((1-methyl-1H-imidazol-2-yl)methyl)(4-sulfamoylphenethyl)amino) acetic acid, [NEt4]2[ReBr3(CO)3] (270 mg, 0.35 mmol) and K2CO3 (78 mg) in MeOH (6.0 mL) was stirred at 90° C. for 4 hrs at a pressure tube. The reaction mixture was purified by Amberchrom (CG-161) eluting with MeOH/H2O to give [Re(CO)3][2-(((1-methyl-1H-imidazol-2-yl)methyl)(4-sulfamoylphenethyl)-amino)acetic acid] (105 mg, 63%) as a white solid. 1H NMR (400 MHz, DMSO-d6) 7.79 (d, J=8.0 Hz, 2H), 7.57 (d, J=8.0 Hz, 2H), 7.36 (d, J=0.8 Hz, 1H), 7.25 (s, 2H), 7.15 (d, J=1.2 Hz, 1H), 4.76 (d, J=16.4 Hz, 1H), 4.58 (d, J=16.0 Hz, 1H), 4.03 (d, J=16.8 Hz, 1H), 3.67 (d, J=16.8 Hz, 1H), 3.65-3.49 (m, 2H), 3.17-3.09 (m, 2H); MS (ESI), 623 (M+H)+.
