Procedure

Concentrated nitric acid (2.5 ml; d, 1.42) was added to a suspension of 1-ethyl-4-hydroxy-6-methyl carbostyril. (1.82g. 0.009 mole) in glacial acetic acid (10 ml) and the mixture warmed to 100°C. The solid dissolved and the 3-nitro derivative immediately solidified as a yellow solid. After cooling the solid was filtered, washed well with water and dried in vacuo over P2O5, m.p. 192°-4°C; (Found; C, 58.16; H, 5.02; N, 11.29; C12H12N2O4 requires; C, 58.06; H, 4.87; N, 11.29%).
