To a solution of 3-iodo-4-methylaniline (1 g, 4.29 mmol) in H2O (25 mL) was added H2SO4 (0.5 M, 25 mL). The solution was heated to 80 C. until all solid dissolved. Then the reaction was cooled to 0 C. and NaNO2 (444 mg, 6.39 mmol) was added in small portions. After 2 hr at this temperature, urea (126 mg, 2.1 mmol) was added at 0 C. The solution was allowed to warm up to room temperature and H2SO4 (0.5 M, 25 mL) was added. The reaction was refluxed for 30 min and cooled down to room temperature. The solution was extracted with EtOAc and Et2O and the combined organic phases were dried over Na2SO4, concentrated, and chromatographied to give the pure product v (800 mg, 80%).
