Reaction Steps

A solution of 2-amino-5-fluorobenzonitrile (136 mg, 1 mmol) and sulfamoyl chloride (114 mg, 1 mmol) in DMA (2 mL) was stirred at room temperature for 2 hours. The reaction was purified by Varian HPLC (10% Acetonitrile/Water) to give N-(2-Cyano-4-fluorophenyl)sulfamide as a pale-white solid. 1H NMR (400 MHz, DMSO-d6) 7.18 (m, 2H), 7.56-7.60 (dd J=8.8 Hz, 2.8 Hz 2H), 9.44 (s, 1H).
