Yield: 93%

Reaction Conditions:

with sulfuric acid;Iodine monochloride in water at 80;

Steps:

Compound 1.
A round-bottom flask equipped with a magnetic stir bar is charged with 4-hydroxybenzoic acid (5.00 g, 36.2 mmol), 10 % H2SO4 aqueous solution (180 mL) andIodine monochloride (17.6 g, 108 mmol) at 0°C. Then, the reaction mixture is heated to80°C and stirred overnight. The precipitated mixture is filtered and washed with sodium bisulfite and water to afford compound 1 (13.1 g, 93% yield) as a white amorphouspowder. NMR 1H (400 MHz, DMSO-d6): 8.30 (s, 1H); 8.14 (s, 2H). NMR 13C (100 MHz,DMSO-d6): 165.1; 146.6; 140.8; 137.5; 86.6; HRMS was not possible due to lowionization of compound 1 by APPI-TOF and ESI-TOF mass spectroscopy.
