Reaction Steps

A mixture of N2-[4-(benzyloxy)phenyl]-4-methylpyridine-2,3-diamine (8.70 g), cyanogen bromide (6.04 g), THF (80 ml) and water (20 ml) was stirred at room temperature for 24 hr. The reaction mixture was poured into saturated aqueous sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was washed with ethyl acetate, treated with activated carbon, and recrystallized from methanol to give the title compound (5.60 g).
