Procedure
0.37 ml of 65 percent nitric acid is added dropwise at room temperature to 1.3 g of 4-hydroxy-3-methoxyphenyl 4-quinolyl ketone. After stirring for 3 hours the reaction mixture is poured into ice-water, adjusted to pH 6 with conc. ammonia and the precipitate formed is filtered. The thus-obtained residue is heated under reflux in 20 ml of acetonitrile, whereupon the crystals are filtered at 0°. There is obtained 4-hydroxy-3-methoxy-5-nitrophenyl 4-quinolyl ketone of m.p. 246°-248°.
