Reaction Steps

To a solution of 6-bromo-2-[N-(2-chloro-4-phenylbenzyl)acetamido]-3-nitropyridine (15.4 g) in dioxane (150 ml) was added 1N aqueous sodium hydroxide solution (43.5 ml) at room temperature and the mixture was heated to 50° C. The mixture was stirred for 3 hr, ice-cooled, and neutralized with 1N hydrochloric acid. Water (300 ml) was added and the precipitated crystals were collected by filtration and dried under reduced pressure to give 6-bromo-2-[N-(2-chloro-4-phenylbenzyl)amino]-3-nitropyridine (13.8 g) as yellow crystals.
