Reaction Steps

A solution of iodine monochloride (25.8 mL, 514 mmol) in water (220 mL) at 0° C. was treated with concentrated hydrogen chloride (87 mL, 2800 mmol) and stirred until the iodine monochloride dissolved. This cooled ICl solution was then added to a solution of p-nitroaniline (71 g, 510 mmol) in water (590 mL) and concentrated hydrogen chloride (50 mL, 2000 mmol) and stirred at 20° C. for 3 hours. The reaction mixture was filtered, washed with water, and dried to give the desired product (132 g, 94%) as a yellow solid. LCMS for C6H61N2O2 (M+H)+: m/z=264.7.
