실험 절차

5.77 g of 5-(p-fluorobenzylamino)-pyridine-2-carboxylic acid are dissolved in 40 ml of water and 20 ml of 2 N aqueous sodium hydroxide. The solution is stirred at room temperature and 3.6 g of 40% aqueous peracetic acid are added. The solution becomes green and within less than a minute a solid separates. Another 3.6 g of said peracetic acid are added and the mixture is stirred for 4 hours. The pH of the mixture is adjusted to 4 with hydrochloric acid and filtered after cooling. The solid is collected and recrystallized from 90% aqueous acetonitrile, to yield the 5-(p-fluorobenzylamino)-pyridine-2-carboxylic acid N-oxide melting at 206°-209°.
