実験手順
Nitric acid (70%), 2.3 mL, was added dropwise to a stirred mixture of 2-hydroxyquinoline (available commercially or by one of the methods described in Beilstein 21, 77) 3.5 g (0.024 mole), in 20 mL of concentrated sulfuric acid at 0° C. The reaction mixture was stirred for 2 hours at room temperature and then poured into ice and water. The resulting solid was collected by filtration, washed with cold water and then digested twice with hot methanol to yield 3 g (67%) of 6-nitrocarbostyril as crystals; m.p. 280°-282° C.
