Procedure

A mixture of 7-(trifluoromethyl)-4-quinolinol (22.7 g, 0.106 mol) and propionic acid (106 mL) was heated to 120° C. Nitric acid (10 mL of 70%) was added dropwise and heating was continued for an additional 2 hours. The reaction mixture was allowed to cool to ambient temperature. The resulting precipitate was isolated by filtration then washed with water and diethyl ether to provide 13.3 g of 3-nitro-7-(trifluoromethyl)-4-quinolinol as an off-white solid.
