Versuchsvorschrift
Following the procedure set forth in Preparation B, 1- phenyl-4-hydroxy-2(1H)-quinolinone was converted to 1 -phenyl-3-formyl-4-hydroxy-(2(1H)-quinolinone. That the expected product was obtained was confirmed by the spectral data: MS: m/e 265 (M·+); NMR (DMSO): δ10.08 (s, 1H, CHO) ppm.
