Procedure
A crude product (1.90 g) of 3-(4-(N,N-bis-(tert-butoxycarbonyl)amino)-2-chlorobenzyl)-5-bromo-2-methyl-3H-imidazo[4,5-b]pyridine was dissolved in 1,4-dioxane (19 ml) and 1N aqueous sodium hydroxide solution (7.0 ml) was added, which was followed by refluxing under heating for 8 hr. The mixture was allowed to cool, neutralized and stirred at room temperature for 30 min. The precipitate was collected by filtration, and washed with water to give 3-(4-(N-(tert-butoxycarbonyl)amino)-2-chlorobenzyl)-5-bromo-2-methyl-3H-imidazo[4,5-b]pyridine (1.45 g) as a pale-gray powder.
