실험 절차

A solution of 4-hydroxy-1-phenyl carbostyril (2.20g.; 0.0093 mole) in glacial acetic acid (10 ml.) was treated rapidly with concentrated nitric acid (2.5 ml. d 1.42) and the mixture heated on a steam bath for 21/2 mins. The red solution deposited a dark yellow solid on cooling which, after dilution with ethanol, was filtered off and washed well with ethanol, m.p. (AcOH -- EtOH) 167° - 169° C. (Found; C, 64.13; H, 3.70; N, 9.85; C15H10N2O4 requires; C, 63.83; H, 3.57; N, 9.92%).
