Procedure

6-Chloro-5,7-dibromo-1-hydroxy-2-(trifluoromethyl)-1H-imidazo(4,5-b)pyridine (0.9 gram) was mixed with ether (15 milliliters) and methyl isocyanate (2 milliliters) and stirred for 15 minutes. Triethylamine (0.01 milliliter) was added, and the solution became homogenous. It was permitted to stand for sixteen hours, diluted with 50 milliliters diethyl ether; washed with 0.5N HCl, water, and saturated NaCl; then dried over magnesium sulfate, and evaporated. The resulting 1-(methylcarbamoyloxy)-6-chloro-5,7-dibromo-2-(trifluoromethyl)-1H-imidazo(4,5-b)pyridine product was recrystallized from chloroform, m.p., 216° C.
