실험 절차

A mixture of 2-amino-5-iodobenzoic acid (3.5 g) and urea (1.56 g) in NMP (15 ml) was heated at 160° C. for 6 hours then cooled. Water (200 ml) was added and the resultant precipitate was collected, washed with water and dried to give the title compound (3.35 g) as a solid. MS (CI+): 289 (M+H)+.
