Reaction Steps
To a mixture of 9.84 g of 2-hydroxy-5-(trifluoromethyl)pyridine and 40 ml of concentrated sulfuric acid, 10.9 g of 70% nitric acid was dropped at 80° C. This mixture was stirred at 80° C. for 1 hour. The reaction mixture was cooled down to room temperature, then, the reaction mixture was poured into ice water. The deposited solid was collected by filtration. This solid was washed with ice water, then, dissolved in ethyl acetate, and washed with saturated saline. The organic layer was dried over magnesium sulfate, then, concentrated under reduced pressure, to obtain 5.22 g of 2-hydroxy-3-nitro-5-(trifluoromethyl)pyridine.
