Participants

Reaction Steps

To 100 mg (0.190 mmol) 2-oxo-3[(4-sulfamoyl-phenyl)-hydrazono]-2,3-dihydro-1H-indole-5-carboxylic acid pentafluorophenyl ester in 5 mL acetonitrile was added 50 μL (5.6 M in ethanol, 0.28 mmol) of a solution of dimethylamine and 20 μL (0.25 mmol) of pyridine, and the reaction was stirred overnight. The solution was concentrated, and the resulting solid was triturated with EtOAc to give the title compound as a yellow solid (39 mg, 53%): mp>230° C.; 1H NMR (DMSO-d6): δ12.71 (s,1H), 11.22 (s,1H), 7.75 (d, J=8.8 Hz, 2H), 7.60 (s, 1 H), 7.58 (d, J=8.8 Hz, 2H), 7.31 (dd, J=1.7, 8.1 Hz, 1H), 7.23 (s, 2H), 6.93 (d, J=8.0 Hz, 1H), 2.95 (s, 6H); APCI−MS: m/z 386 (m-H). Anal. Calcd for C17H17N5O5S.1/2H2O: C, 51.51; H, 4.58; N, 17.67. Found: C, 51.69; H, 4.25; N, 17.63.
