Procedure

A solution of 3-(1H-imidazol-1-yl)phenol (8 g, 0.05 mole) in acetonitrile was treated in an ice bath with sulfamoyl chloride generated from 0.075 mole of chlorosulfonyl isocyanate followed by 0.075 mole of triethylamine. After stirring overnight at room temperature, TLC, and 1H NMR of a sample showed starting material still present. The reaction was then treated with another 0.075 mole each of sulfamoyl chloride and triethylamine for another night.
