실험 절차

To an ice-cooled, stirred solution of 5-Aminosalicylamide (10.0 grams, 0.073 mol), in 300 mL of water containing NaHCO3 (42.0 grams, 0.5 mol), iodoacetyl chloride (18.4 grams, 0.09 mol) is added dropwise over 15 min. After stirring at 0-5° C. for 1 hr., the solution is acidified with cold 6 N HCI. The precipitate is collected and dried in vacuo over NaOH pellets, to afford 21.3 grams (96% yield) of crude 5-(iodoacetamido)salicylamide.
