Reaction Steps

To a cooled (0° C.) solution of (Z)-N,N-dimethyl-N′-(4-(2-methyl-4-nitrophenoxy)pyridin-2-yl)formamidine (1.00 g, 3.33 mmol) in methanol (5 mL) was added pyridine (0.54 mL, 6.66 mmol) and hydroxylamine sulfonic acid (0.427 g, 3.66 mmol). After stirring at room temperature for 2 hours, the precipitate was filtered to provide the product (0.442 g, 49%) as white solid.
